USB problems

Nothing I can find on wikipedia mentions the known problems with the USB hardware on the Raspberry Pi SoC chip. Please include details of this problem so that others like myself do not feel burned by purchasing something that does not live up to expectations. Details are available at: http://hardware.slashdot.org/story/12/08/24/2228251/serious-problems-with-usb-and-ethernet-on-the-raspberry-pi http://www.raspberrypi.org/phpBB3/viewtopic.php?f=28&t=39175 — Preceding unsigned comment added by 68.95.141.46 (talk) 10:15, 26 July 2013 (UTC)

Is this an old issue which has since been corrected, or is it current? The material can be added to the article if it is cited in reliable sources and is encyclopedic. -- Trevj (talk) 13:45, 26 July 2013 (UTC)
I believe this is the the same issue that resulted in the article being protected here. So far I don't think any reliable sources have been produced - it has so far been mostly POV pushing. Яehevkor ✉ 14:21, 26 July 2013 (UTC)
There are some sources that cover this:

Are you suggesting that a link to the organization's own forum where people actively working on the problems are discussing it is not reliable??? — Preceding unsigned comment added by 68.95.141.46 (talk) 23:28, 26 July 2013 (UTC)

Largely, no. See WP:SPS. Sources should be both reliably published and ideally independent of the subject. Яehevkor ✉ 19:22, 27 July 2013 (UTC)
Let me check... Yup, I still have the ability to go on the official Raspberry Pi forum and claim that the Raspberry Pi is made out of actual raspberry pies, and then to make the same claim on Wikipedia using the official Raspberry Pi forum as a source. Do you see the problem? --Guy Macon (talk) 20:24, 27 July 2013 (UTC)
mmmm raspberry pi pie -- Taroaldo ✉ 20:40, 27 July 2013 (UTC)
Just licked mine and I can confirm, they're made of raspberry pies. Яehevkor ✉ 20:59, 27 July 2013 (UTC)

If you bothered to read the thread I linked, you might notice it is 6 pages of posts from a large number of people in a locked thread. Several of the people work for the organization and this can be verified.

So, the article will be edited to include at the very least the info from Guy Macon's links above? Or are you too busy treating me like a child to bot her? — Preceding unsigned comment added by 68.95.141.46 (talk • contribs) 22:00, 27 July 2013 (UTC)

Insulting the other editors here is unlikely to help. Everybody here wants this article to be accurate, but we have standards for what is and is not acceptable as a source, and neither Slashdot nor the Raspberry Pi forums qualify. Give us some sources that meet the criteria listed in WP:RS and WP:V and we will be glad to add a section to the article. --Guy Macon (talk) 07:59, 28 July 2013 (UTC)

Edit request on 30 July 2013

Hi everyone. I am new to wikipedia edit protection system, which I find very appropriate btw. I would simply like to add my RaspberryPI distro project on the page. It is called pipaOS and you can visit it here: http://pipaos.mitako.eu. I think the "Multi-purpose light distributions" section would be appropiate. Thanks in advance. Albert Skarbat (talk) 10:25, 30 July 2013 (UTC)

Not done: Generally we only add something to a lists if it is notable and there is already a Wikipedia article about it. RudolfRed (talk) 04:52, 3 August 2013 (UTC)

Edit request on 7 August 2013

The opening paragraph says that: The Foundation's goal is to offer two versions, priced at US$25 and US$35.

This is obsolete, both models are offered. I would suggest the page is edited to: "The Foundation offers two versions, priced at US$25 and US$35" Arthurs (talk) 19:58, 7 August 2013 (UTC)

Done. I didn't use your exact wording but I think it now clearly shows both prices are offered. Sarahj2107 (talk) 15:07, 9 August 2013 (UTC)

BLOB problem / device can't boot without

It should be more clear and easier to understand that the device is useless without the BLOB by broadcom, because it can't boot without. At the moment this is not clear for an audience without much knowledge about the problem, like students and kids who make their first "steps" with the RaspPi in school.

I don't know how to do it, because "Driver API" might not be the right place. So a separate section which explains the problem would be better (IMHO).

80.187.109.172 (talk) 00:52, 25 August 2013 (UTC)

Do you have any reliable sources for this? Please be aware that Wikipedia articles are encyclopaedia articles and not technical manuals, material must be supported by reliable sources (published news articles for example, not forums). Яehevkor ✉ 13:16, 25 August 2013 (UTC)
This is like saying that a desktop computer is "useless without the video BIOS provided by nVidea". Because that is what the "blob" is, it is the equivalent of the video BIOS. and other computers also cannot boot without the video BIOS contained in ROM on the video card. This isn't an issue as the blob is freely distributed with the PI, just as the video BIOS is freely distributed with the video card. Just as normal users do not care about the BIOS in their video cards, why should PI users care about this non-problem. You can remark about this technical difference, but not in the context of a "problem". Mahjongg (talk) 12:52, 26 August 2013 (UTC)

Raspberry Pi audio problems

There seems to be numerous and consistent reports that the audio of the first batch of Raspberry Pi boards produce numerous clicks and popping. There are a number of work-a-rounds on the web, a patch that results in some buzzing instead of "clicks", and even a kickstarter project that is a dongle that plugs into the board for an attempt at better audio. I wanted to get other's views and inputs on this before I add a new section to the article. In fact, I originally came to this article looking for information concerning this apparent problem with the boards. Here is a video of apparently loud clicking coming through, Perhaps the section could go into how audio is generated on the Rapsberry Pi (i.e. via the PWMs) Nodekeeper (talk) 09:43, 27 August 2013 (UTC)

The clicking problem was caused by turning the PWM engines on only when analog audio was needed. It was solved with a software update months ago. HDMI audio wasn't affected. Mahjongg (talk) 12:52, 27 August 2013 (UTC)

FSF free hardware criteria and Videocore

Hi, https://github.com/hermanhermitage/videocoreiv According to other sources the Pi doesn't fulfill the FSF free hardware critera. Maybe that should be included in the article (or at least be included when it will be). I'm not sure the above link shows any indication that they are making any progress on that (maybe not intented to?). But there seems to be some progress in "freeing" (parts of?) the GPU binary blob (bootloader/firmware?). I haven't waded throught this all open source project but there might be something to report from there. comp.arch (talk) 10:35, 29 August 2013 (UTC)

As far as I can tell, the RPF has never even hinted that they would ever be open hardware. Some of their competitors (Odroid, Wandboard) are open hardware, but they have more features and a higher price. --Guy Macon (talk) 13:34, 29 August 2013 (UTC)

No new version (Model C or otherwise) of the RaspberryPi until Sept 2015 at earliest

Should a note be placed in the article to state that there will be no new version of the RaspberryPi until September 2015 at the earliest? See http://www.raspberrypi.org/phpBB3/viewtopic.php?f=63&t=56598 "Eben Upton, Founder, has stated in public that he would expect a NEW board between two and three years from now (Sept 2013)." — Preceding unsigned comment added by 166.64.3.2 (talk) 04:26, 1 October 2013 (UTC)

Android

It should be noted that android has no working (or rather working well) builds. I don't believe Broadcom ever released the 4.0 image for it either. — Preceding unsigned comment added by 24.186.1.167 (talk) 01:17, 18 November 2013 (UTC)

Open Hardware?

Is it completly open hardware or not? — Preceding unsigned comment added by 87.78.74.104 (talk) 03:34, 2 March 2014 (UTC)

No! there are still remnants of the hardware that are and will stay undocumented, (because the RPF doesn't actually own, nor has the right to release, those IP). It has also never been the intention of the RPF that the PI would become "open hardware". But TBH I would never had thought they would have released the documentation of the VideoCore, so who knows. Mahjongg (talk) 14:48, 2 March 2014 (UTC)
Link to yesterday's blog entry ("Earlier today, Broadcom announced the release of full documentation for the VideoCore IV graphics core, and a complete source release of the graphics stack under a 3-clause BSD license."):[1]
If you want an open source hardware board roughly comparable to the Paspberry Pi, you might want to look into the Odroid U3 or X2.[2][3] Of course it is worse than the RP in some ways and better in other ways, so it may not meet your needs.
Related question; does this page make the licensing for the Raspberry Pi hardware, software, and documentation clear? --Guy Macon (talk) 17:13, 2 March 2014 (UTC)

Credit card sized?

Image1Source1, Image2Source2, Image3Source3. As an aside, look what you can do with a board that small. --Guy Macon (talk) 00:35, 23 March 2014 (UTC)

The rpi in real life is a little bigger than credit card. I do not have the electronic caliper but it is about 56mmx85mm. I have measured it manually + Source. Therefore I think it should be edited to show true dimensions Armata007 (talk) 14:31, 23 March 2014 (UTC)
Please read WP:OR and WP:V. --Guy Macon (talk) 17:38, 23 March 2014 (UTC)

I take issue with it being described as credit-card sized on the basis that even if it's x and y dimensions were that of a credit card, it's z dimension isn't anywhere near that size. Wallet-sized might be a better description, or perhaps simply rephrasing it to "about the length and width of credit card." Better yet, just list it's actual dimensions. — Preceding unsigned comment added by 184.20.43.154 (talk) 23:34, 23 June 2014 (UTC)

It's actually about the size of a packet of cigarettes or tampons. It is about the size of 15 credit cards. Greglocock (talk) 01:36, 25 June 2014 (UTC)

...and to be honest, is its size the most important fact about it, such that it should be in the first line of the lede? Greglocock (talk) 01:40, 25 June 2014 (UTC)

It's not about the size in millimeters, or the thickness. That's all nonsense, its to give people a mental picture of the relative size of the device, much tinier than previous computers. And at launch time it was big enough a deal that almost all media cared to mention its size which was most easily compared to a credit card, and in fact a credit card was used as inspiration for how big it should be. Obviously, especially with parts sticking out, its not exactly to the mm precisely as big as a credit card, and nobody expects when you say "its credit card sized" next to a picture of it that is only a few mm high, but people can get a much better idea how big it is based on a mental impression of the size of a credit card. It's size was and still is one of the distinguishing features of the raspberry PI. Mahjongg (talk) 10:54, 25 June 2014 (UTC)

Its small size is unexceptional for an integrated mobo, and I really don't think it is the most important fact about the computer so why is it the FIRST thing mentioned in the lede? Surely its low cost, open design, expandability and wide range ofOS available for it are far more significant than a misleading size comparison. Greglocock (talk) 21:00, 25 June 2014 (UTC)
Dont flog a dead horse, when it came out (in the current form) almost all the media reported it was "credit card sized", perhaps you don't like it has that reputation, but the fact is that its has. here are just a few links to old articles about its introduction that mention the credit card size of the raspberry PI [4][5][6][7][8] Deal with it! Mahjongg (talk) 22:50, 25 June 2014 (UTC)
o reely. i bet most people were more impressed by the low cost than the small size. Anyway, you want it your way, I'm not going to bother arguing any mor sGreglocock (talk)
Yes really - this appeared just today on the New York Times website: starting with "Raspberry Pi, a tiny computer the size of a credit card, ..." Regards, Lynbarn (talk) 21:37, 26 June 2014 (UTC)
I suppose it is inconceivable that a journalist used wiki as a ref when writing the story? Greglocock (talk) 01:00, 29 June 2014 (UTC)
No, but the media talked about it even before this article was written. Also its more conceivable that the media are following the official FAQ for the raspberry PI! [9]
If it really isn't credit-card sized - which it isn't - we shouldn't just copy that claim just like any ole newspaper. How about something like "frequently referred to as credit-card sized" or "footprint close to that of a credit-card"? Zac67 (talk) 18:49, 30 June 2014 (UTC)
What would it matter if its a millimeter off from the official size of a credit card, the raspberry PI foundation in its FAQ calls it "credit card sized" not because it claims its size is for some obscure reason precisely identical to a credit card, but simply because calling it that gives the reader an immediate impression of its relative size. All the talk about it not being -exactly- to the millimeter "correctly" sized is simply splitting hairs. There is simply nothing wrong with calling it "credit card sized". Mahjongg (talk) 08:43, 2 July 2014 (UTC)

With the recent release of the Raspberry Pi Compute module - it is now available in a smaller size - using the DDR2 SO-DIMM form factor. Regards, Lynbarn (talk) 09:23, 1 July 2014 (UTC)

Manufacturing locations

The lede states: The Raspberry Pi is manufactured in two board configurations through licensed manufacturing deals with Newark element14 (Premier Farnell), RS Components and Egoman. Is this actually the case? my understanding is that manufacture is by Sony at their Welsh plant, on behalf of the Raspberry Pi Foundation, and these are distributed world-wide (except China) by Farnell and RS. Ergoman manufacture for the China?Taiwan market alone. If this is confirmed, I think it should be made clearer. Regards, Lynbarn (talk) 19:22, 2 July 2014 (UTC)

Versions

We need a clear new section, with explanation and diagrams to show the differences between versions A, B and B+. What will the next one be called? B++ or C- ?

Lehasa (talk) 17:11, 19 July 2014 (UTC)

The RPF has consistently used BBC Micro nomenclature, like models A, B and B+, so if there will ever will be a new model that deserves the title it will be called a "Model C", or perhaps "Master". Mahjongg (talk) 19:27, 24 July 2014 (UTC)

Hardware Random Number Generator not yet mentioned

My Raspberry Pi rev. B has a HRNG I do not see mentioned in the article. See: http://scruss.com/blog/2013/06/07/well-that-was-unexpected-the-raspberry-pis-hardware-random-number-generator/ I agree with the author of https://sites.google.com/site/astudyofentropy/project-definition/raspberry-pi-internal-hardware-random-number-generator that this makes the RPi a great (and very cheap) source for obtaining cryptographic quality random numbers.

Core chip : also from Samsung

Broadcom is not the only provider for the core chip. I read a Samsung K4P4G324EQ-RGC2 on my newly bought Pi B+. The B+ used as illustration seems also to be carrying a Samsung chip. The multifunction chip near USB ports is an SMSC LAN9514-JZX. Perhaps some "BOM guru" could enlighten us on hardware details as seen on the B+.

Core CPU chip is NOT memory or peripheral chips. • Sbmeirow • Talk • 00:51, 23 August 2014 (UTC)
You can't actually see the SoC since the RAM chip is stacked on top. 09:20, 23 August 2014 (UTC)


OP, what you call the "core" chip isn't the Broadcom chip! Its the Package on Package (PoP) DRAM chip that is stuck on top of the actual broadcom SoC, which is exclusively from broadcom! The Samsung chip is just RAM. Mahjongg (talk) 16:06, 23 August 2014 (UTC)

Citation overkill

I came to this article because I want to learn about RaspberryP Pi, but the article is difficult to read because of over-referencing. The opening line "Raspberry Pi is a credit-card-sized single-board computer developed in the UK by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools" does not need five references. This is out out of line with WP:LEAD and with WP:REFBLOAT. Not only is there severe reference overkill, but their use contradicts WP:NOTREPOSITORY and WP:NOTMANUAL. I suggest these guidelines be used to make this article more readable. There are 88 references which point into www.raspberrypi.org which goes against WP:USEPRIMARY. --Cornellier (talk) 17:18, 3 August 2014 (UTC)

Unfortunately this change remove a lot of content as well, leaving some sections somewhat garbled. 80.4.146.162 (talk) 13:17, 12 September 2014 (UTC)

For example ... ? --Cornellier (talk) 14:18, 12 September 2014 (UTC)
The one that made me look in the first place was "...main programming language, (via the ..." - The text "BBC BASIC" use to be after the comma there. "A lot" may have been an exageration; certainly some content was lost along with the citations. Unfortunately the wikipedia diff makes this quite hard to unpick. Elder pegasus (talk) 14:26, 12 September 2014 (UTC)

Multiple Infoboxes

I added 2nd infobox subset dedicated to new RPi2 to make it easier to understand, because packing too much in ONE infobox is very confusing. I have used this method in other articles, such as Keystone Pipeline, and I've seen it used in some other articles. Some fields won't exist in the 2nd infobox (i.e. logo). I haven't removed the RPi2 info from the 1st infobox yet, just in case everyone threw rocks at the 2nd infobox. • Sbmeirow • Talk • 00:18, 3 February 2015 (UTC)

I'm not sure if this path is working or not? Should we merge the infoboxes back or keep going on this path? • Sbmeirow • Talk • 11:00, 3 February 2015 (UTC)
It seems to look better after I moved 3 photos away from the infoboxes. I also have a feeling the infobox split will look better after someone adds a photo of the RPi2. • Sbmeirow • Talk • 12:01, 3 February 2015 (UTC)
I put in a request to move the "power" field in the infobox template to a better location, and it was fixed by another user today. • Sbmeirow • Talk • 22:51, 3 February 2015 (UTC)
According to the article the Power consumption of the RPi 2 is 4.5 to 5 watts "Upton says it uses up to 1 watt more than the BCM2835".[10]. --MarsRover (talk) 18:03, 5 February 2015 (UTC)
There should really only be one infobox. I also think they could do with a trim, especially removing the listing of all the Linuxs distros. As MOS:INFOBOX says, "less is more!" Stickee (talk) 05:26, 10 February 2015 (UTC)
Changed power range, shortened CPU info, shortened Linux info, sent request for RotateBot to rotate the RPi2 photo (so it will take up less vertical space) (actually we need a better photo). It was 1 WEEK until you posted a response about the infoboxes, so I assume most people don't care or feel its ok, otherwise they would've thrown rocks at me sooner. Since this article supports both RPi1 and RPi2, and I assume there will be more RPi2 models, then its worth splitting the infobox now. All the RPi1 info is not easy to tell which is which, so throwing RPi2 into the mix makes it even harder to understand. Thanks for the response. • Sbmeirow • Talk • 09:11, 10 February 2015 (UTC)
Thanks, it looks a little better now with the long list of distros gone. Although I still believe a single infobox may be better. What's your opinion on how the iPad article deals with this issue? Stickee (talk) 09:54, 10 February 2015 (UTC)

The photosensitivity paragraph

Last night, I made this edit (plus two smaller clarifying edits to the same paragraph right afterward), and User:Sbmeirow reverted it only six minutes later, including restoring a factually incorrect statement that I'd corrected. This is what I wrote:

In February 2015, a switched-mode power supply chip, designated U16, of the Raspberry Pi 2 model B version 1.1 (the initially released version) was found to be vulnerable to flashes of light,[1] particularly the light from xenon camera flashes and green[2] and red laser pointers. However, other bright lights, particularly ones that are on continuously, were found to have no effect. The symptom was the Raspberry Pi 2 spontaneously rebooting or turning off when these lights were flashed at the chip. Initially, some users and commenters suspected that the electromagnetic pulse from the xenon flash tube was causing the problem by interfering with the computer's digital circuitry, but this was ruled out by tests where the light was either blocked by a card or aimed at the other side of the Raspberry Pi 2, both of which did not cause a problem. The problem was narrowed down to the U16 chip by covering first the system on a chip (main processor) and then U16 with opaque poster mounting compound. Light being the sole culprit, instead of EMP, was further confirmed by the laser pointer tests,[2] where it was also found that less opaque covering was needed to shield against the laser pointers than to shield against the xenon flashes.[1] The U16 chip seems to be bare silicon without a plastic cover (i.e. a chip-scale package or wafer-level package), which would, if present, block the light. Based on the facts that the chip, like all semiconductors, is light-sensitive (photovoltaic effect), that silicon is transparent to infrared light, and that xenon flashes emit more infrared light than laser pointers (therefore requiring more light shielding),[1] it is currently thought that this combination of factors allows the sudden bright infrared light to cause an instability in the output voltage of the power supply, triggering shutdown or restart of the Raspberry Pi 2. Unofficial workarounds include covering U16 with opaque material (such as electrical tape,[1][2] lacquer, poster mounting compound, or even balled-up bread[1]), putting the Raspberry Pi 2 in a case,[2] and avoiding taking photos of the top side of the board with a xenon flash. This issue was not caught before the release of the Raspberry Pi 2 because while commercial electronic devices are routinely subjected to tests of susceptibility to radio interference, it is not standard or common practice to test their susceptibility to optical interference.[1]

This is what Sbmeirow reverted it to:

In February 2015, the U16 switched-mode power supply chip of the Raspberry 2 was found to be vulnerable to Xenon light, from for example the flash of many camera phones. The U16 chip seems to be raw silicon without a plastic cover, and since covering the chip with non-conducting shielding still blocks the effect, the effect seems to be due to visible light, possibly based on the photoelectric effect.<ref>http://www.raspberrypi.org/forums/viewtopic.php?f=28&t=99042</ref>

My version was superior in the following ways:

  • It provides more information, explaining the mechanism of the problem and how people investigated it.
  • It adds a second reference.
  • It wikifies the existing reference (which was just a URL before).
  • It corrects "photoelectric effect" to "photovoltaic effect"; the photoelectric effect is the release of electrons from illuminated metal in a vacuum (obviously irrelevant), while the photovoltaic effect is the disturbance of electrons in a semiconductor by light (what's happening in U16).
  • It clarifies that the chip is designated U16 in the context of the RPi 2, rather than being a type of chip known as U16.

It was inferior in the following ways:

  • It is longer.

I knew at the time that it was long, and I expected other editors to shorten it and/or make a section for it, but I didn't expect anyone to just delete it for being too long, completely ignoring every advantage my version had, especially factual accuracy. This was also time-sensitive: I wanted to get factually correct and complete (as much as was known) info available before news sources started writing articles about the problem. Several such articles were published today. Most of the ones from technical sources didn't mistakenly mention the photoelectric effect (even though the Raspberry Pi Foundation article they quoted did), but the BBC article and the Belfast Telegraph article did. The BBC even explained that the photoelectric effect earned Einstein his Nobel Prize (though explained the effect incorrectly), so they probably came to Wikipedia at least for that. I haven't (can't) read every article written about the problem, but I expect the several I read are representative (first page of Google News results for 'raspberry pi'). Importantly, the two mainstream articles got it wrong, and they're the ones that people who aren't already familiar with the issue (or Raspberry Pi in general, or the two effects) are more likely to read. So, I think if the correct information had remained in the article for the rest of the day, rather than being replaced with a reiteration of the mistaken reference to the photoelectric effect, many laypeople being given incorrect info could have been avoided. (Note that I'm not saying anything about the laypeople's opinions of the Raspberry Pi 2 in light of this issue. It's not Wikipedia's job to promote products, but it is Wikipedia's job to provide correct and reasonably complete information.) I have now reverted it to my version and I expect that my version will be the basis for future edits of this paragraph for the reasons listed above. Ian01 (talk) 10:16, 10 February 2015 (UTC)

This might be a good time for you to take a look at WP:BALASPS and WP:RECENTISM (in reference to the length). The longer version gives undue weight to the the U16 issue, and as such makes it seem like a bigger issue than it is.
There are certainly improvements, but most of them (bullet points 2-5) could be made to the shorter version without increasing it's length. Stickee (talk) 10:56, 10 February 2015 (UTC)
It is excellent information, seriously I love detailed information, but...
  1. I reverted it because it was TOO LONG, per WP:BALASPS, not because the previous text was better.
  2. If you knew it was too long, then why didn't you shorten it before posting?
  3. If you knew it was too long, then why did you restore it a 2nd time without shortening it?
  4. It's NOT the responsibility of other Wikipedia editors to be your personal "Copy Editor". It is your responsibility to shorten it.

Redesign table?

I think it's time to rewrite the table for the versions. Raspberry Pi 3 is out and the width of the table is getting two big. Either split it off into separate tables (for example Model A, Model B and compute node into separate tables) or flip the table and have the versions be the rows and the characteristics the columns (probably worth having more than one tables here too). — Preceding unsigned comment added by Alexandrujuncu (talk • contribs) 07:45, 29 February 2016 (UTC)

Lead section - specs of all three units or condense

WP:LEAD says "Editors should avoid lengthy paragraphs and over-specific descriptions, since greater detail is saved for the body of the article."

Given the number of times there have been updates to the Pi, I'd argue that details of the specifications of the A, B, A+ and B+ are less interesting than a longer term comparison of the latest (Pi 3) to the first (eg "10 times more powerful" is something non-technical readers understand on first read).

-- Callinus (talk) 08:31, 1 March 2016 (UTC)

Agree, it has become overly technical. Most of the specification is better handled elsewhere. I'd be inclined to go further to "avoid difficult-to-understand terminology and symbols." and not mention the specifics on which chips are used simply saying there is three are generations and they uses a SoC. The lead should be simple enough that someone who knows nothing has an idea of what a Pi is. --Salix alba (talk): 09:05, 1 March 2016 (UTC)
Agree - I made reference to this in the edit comment on this revision but never got round to following it up. I think really at this point most mentions of specific technologies could be removed from the lead, as most are not common between different versions and listing different technologies is certainly excessive detail. TSP (talk) 11:24, 1 March 2016 (UTC)
I've just taken a look over at the ZX81 article for comparison, and I think that (although rather lacking in sources) gives a good idea of the sort of thing we should be aiming for - far more about background, design principles and social impact; far less about specific chip names and versions. (Perhaps with a 'dead' technology it's easier to achieve perspective on what's important.) TSP (talk) 11:28, 1 March 2016 (UTC)

Manufacture location(s)?

Can anyone source stats on where most Pis are now manufactured? I can find sources from 2013 saying that the plan was in future for most of them to be manufactured in Wales, but nothing more recent saying if that is actually now the case. If it is, it might be worth mentioning fairly prominently as primarily-UK tech manufacture is now fairly unusual (while still not being the same as the Pi having been *developed* in Wales, which it wasn't). TSP (talk) 14:54, 11 April 2016 (UTC)

Models

It would be great if the article could provide enlightenment on the general idea behind the different models. This is very confusing to newbies. To my knowledge, the Bs and B+s are the consumer versions, whereas the As and A+s are the industry models, correct? Thanks, Maikel (talk) 14:35, 20 March 2016 (UTC)

I've updated the Specifications table to better reflect the division of generations. I think most of the confusion arises from the fact that the second version of the Model B was referred to as the "Model B +", whereas subsequent revisions deprecated the "+" numbering scheme, and instead use numberic delineation, such as "2 Model B" and the "3 Model B". So there are four versions of the Model B, named like this:
  1. Raspberry Pi Model B
  2. Raspberry Pi Model B +
  3. Raspberry Pi 2 Model B
  4. Raspberry Pi 3 Model B
It would have probably been easier if they'd just named them the "Rasberry Pi Model B 1", "Raspberry Pi Model B 2", etc.
InternetMeme (talk) 11:50, 16 May 2016 (UTC)

I was about to add new info blocks for the A,B and A+ versions, as I thought they were missing, before realising the information is all under the B+ model info block. I think however, as the B+ v1 RPi and the 2 and 3 RPi's look more or less identical (2x2 stacks of USB on the right), I think it's silly listing them in the 3 blocks. The Rpi B was the most available Rpi for several years (I have 2), and the Rpi A (only a single USB and no RJ45 connector) was the equivalent to the Zero for the same length of time. So I'm not sure why the most similar, older model, the B+ is displayed, over the distinctive A and B models. Please send me a message if someone wants me to take a more uniform photo of my RPi A, rather than the oblique one I listed sibaz (talk) 09:54, 22 March 2016 (UTC)

As an aside, when referencing the RPi, it's useful to know the original model B See Photo at elinux.org included a populated JTAG header, next to the SVideo connector. This gets in the way, if you try to use some cases (such as the PiBow). Hence I'd guess it's worth being pointed out, in reference material, as it can be a significant different. sibaz (talk) 10:00, 22 March 2016 (UTC)

OS Support

Pi is developing quite the range of OS support now. I've hacked in (cough) Diet Pi as it is, in my experience, a stable and very versatile solution. I'm using it for a VPN, DNLA server and even a three variations of Minecraft servers distributed over just two machines. It also comes with at least two desktops (Mate and LXDE) and a bunch of other stuff. Someone should make a page. I'm not connected to the project (save for being a patron) but I believe it deserves a mention. — Preceding unsigned comment added by 82.16.170.111 (talk) 21:00, 10 June 2016 (UTC)

What is "overvolt"?

In section Overclocking there is "6 overvolt", "2 overvolt" and "0 overvolt". What does that mean? It is not clear at all from the context.

For instance, is there an implicit unit, like 0.1 volt? In that case, shouldn't the voltage be stated instead, like 0.6 V overvoltage? --Mortense (talk) 10:17, 22 July 2016 (UTC)

This explains better than I ever could exactly what overvolt is in regards to overclocking. However, you're correct about the unit inclusion, I imagine it should read 2v overvolt -- samtar talk or stalk 10:25, 22 July 2016 (UTC)
Isn't the correct term overvoltage (over + voltage)? Wiktionary has it, but in a slightly different context. Or perhaps as an action, overvolting, as in Wikipedia article Dynamic voltage scaling.
BTW, the unit must be lower than 1 volt. 6 volts is way too much; it would fry the electronics. It could be 0.01 volt, +0.06 V for the core voltage of 1.2 V (5% relative change). Or it could be some entirely different unit. --Mortense (talk) 12:45, 22 July 2016 (UTC)
Looking closer, yes I think you're right there - I personally would write it as overvolting the whatever by 0.2 volts? -- samtar talk or stalk 14:04, 22 July 2016 (UTC)

RFC: clear floats before specs table

I added a div style="clear: both" before the Specifications section to create enough vertical space for all floating figures to render. The specifications table, which has become huge lately, can then take up the full page width. I think this looks a lot better.

PR speak - WP:NPOV

Encyclopedic articles should not parrot the company's or organization's talking points and PR slogans. Intentions, motives, and the developers' overall desire to make the world a better place (sorry for the sarcasm) are not encyclopedic facts. Product achievements and successes should not be praised empathically, but described in a neutral and uninvolved tone. Of course editors are excited about such new technologies and developments, but these positive opinions should not be reflected in the article's main text (except from a properly sourced and attributed "Reception" section). I'll try to tone down some of the problematic phrases, but more care should be taken to meet the requirements of WP:NPOV. GermanJoe (talk) 19:40, 25 January 2018 (UTC)

Commercial use

Proogs (talk) 11:18, 8 February 2018 (UTC)

Hi; I don't edit wikipedia much other than minor edits, so I hope this is right place to ask this.

I added some info about a commercial use for a Pi - the Robe MiniMe - that's been reverted. I'd linked to the product's own webpage as proof of its inclusion in the product but I think you need a more independent source. Would an article in the industry press be sufficient? I've found PLSN's road test of the product - would this be a better reference? PLSN's article It actively talks about the use of the Raspberry Pi as a media server within the unit.

If it's OK, perhaps someone can revert the text back again with this as the reference, please? Thanks.

The information needs a source to confirm it is notable. An industry source may be suitable, better than first party source. Also, the content shouldn't be seen as advertising a product - something Wikipedians are particularly vigilant about. More information at Wikipedia:Citing sources. Feel free to add content back if you have suitable sources. Jonpatterns (talk) 12:05, 8 February 2018 (UTC)

Proogs (talk) 01:38, 9 February 2018 (UTC)

Thanks - it's rather difficult to talk about commercial use of something and to name the product without someone taking it as an advert. Is there an accepted way of phrasing something such that it mentions a commercial product without it being misinterpreted? Perhaps I should just be nonspecific when mentioning it - but then it becomes a useless addition to the 'commercial' section!

infobox name

I noticed that the infobox name is "Raspberry Pi 3 Model B+ (latest version)" - this is incorrect, as the article is "Raspberry Pi" and the infobox title should reflect this. I went into the article to change it, and see the following:

|name = Raspberry Pi 3 Model B+ (latest version) <!-- Please don't rename -->

What rationale is there for there to be an insistence on "Please don't rename"? Having the title as "Raspberry Pi 3 Model B+ (latest version)" is a bad thing - the B+ doesn't even have a section within the article, yet we announce it at the top.

The model history is covered in the Overview section - it's not the job of the infobox to list the latest model available. Chaheel Riens (talk) 13:38, 19 March 2018 (UTC)

Agreed. The image caption should be model specific, the infobox title shouldn't. Andy Dingley (talk) 14:04, 19 March 2018 (UTC)

Agree, both the amount of detail and its placement as a prominent lead paragraph are undue weight. Several of these numbers are also only based on the organization's information from press releases and interviews, and do not represent significant lead-worthy milestones (which should be established by in-depth coverage in truely independent non-PR publications).
