Hardware History - guide to the Raspberry Pi models.

Low-level Peripherals - using the GPIO and other connectors.

Expansion Boards - GPIO plug-in boards providing additional functionality.

Screens - attaching a screen to the Raspberry Pi.

Cases - lots of nice cases to protect the Raspberry Pi.

Other Peripherals - all sorts of peripherals used with the Raspberry Pi.

Which Pi have I got?

You can try to check which Pi you have by looking at the board layout and the components used, but this might not be very easy or reliable. Since the range of Pi models gives a significant difference in performance, this can be quite important, especially if not buying through the approved channels.

Board Revision History

The reliable way to find out your board revision is to use the following command:

cat /proc/cpuinfo

You will see your device data including:

 Hardware	: BCM2708
 Revision	: 0003

If you see a "1000" at the front of the Revision, e.g. 10000002 then it indicates[1] that your Raspberry Pi has been over-volted, and your board revision is simply the last 4 digits (i.e. 0002 in this example).

Another method to obtain just the revision ID (also removes any overvoltage mark):

 cat /proc/cpuinfo | grep 'Revision' | awk '{print $3}' | sed 's/^1000//'

or more simply:

 awk '/^Revision/ {sub("^1000", "", $3); print $3}' /proc/cpuinfo

or use a web tool

 rev=$(awk '/^Revision/ { print $3 }' /proc/cpuinfo) && curl -L perturb.org/rpi?rev=$rev

Significant design changes

The following changes were made in the early models.

ECN0001

ECN0001 is the request to not fit D14 and to replace poly-fuses F1 and F2 with 0 ohm.

D14 Removal

D14 can interfere with some CEC devices if the Pi is left plugged in and unpowered. The benefits of having it are minimal so it was removed.[2]

F1 & F2 Replacement/Removal

F1 & F2 can cause problems with some USB devices which draw high current. In particular due to the recovery characteristics of the poly-fuses, it can take a while to recover their low resistance state afterwards, adding additional problems for other devices (lower voltage on the USB bus).

Model B Revision 2.0

This model is based on a new PCB layout that includes previous build fixes from ECN0001 such us removal of the poly-fuses in series with the +5V power for USB devices, and other fixes reported by the community such as the erroneous connection of the LAN9512 VDD18CORE pins to the +1V8 power plane, addition of the 8-pin P5 header (non-populated) for extra GPIO pins, addition to the 2-pin P6 header (non-populated) for a RESET button, and other changes and improvements reported in more detail [3].

Colour Variations

The vast majority of the Raspberry Pis produced have a Green PCB, but Pis produced by Egoman_Technology_Corp (only available in the Far East) have a Red[4] PCB, and RS Components produced a limited edition of anniversary Pis in Blue[5]. The red-PCB model sold in the far east is functionally the same as the standard green-PCB model sold in the rest of the world, but it has not passed the compliance testing required for sale in those areas (for example, FCC in the USA, and CE Mark in the EU).

Current models

The following models can be considered current due to the large numbers that were shipped. They may be available from commercial suppliers or as pre-owned models.

Raspberry Pi Compute Module

The RPi compute module

Announced on 7th Apr 2014 Full announcement from the Raspberry Pi Foundation.

The compute module contains the guts of a Raspberry Pi (the BCM2835 processor and 512 MB of RAM) as well as a 4 GB eMMC Flash device.

This is integrated on to a small 67.6x30mm board which fits into a standard DDR2 SODIMM connector.

Raspberry Pi Model A Full Production Board

  • As of Feb 2013, available from distributors in Europe but not North America
  • Board has 256 MB of RAM rather than the originally planned 128 MB[6]
  • The Foundation produced a small Beta batch before handing manufacturing over to RS and Farnell
  • The Model A boards actually use the identical Revision2.0 PCB as Model B boards, just with a different selection of components fitted (full details available from the schematics). AFAIK no Model A boards using the Revision1.0 PCBs were ever publicly available (or indeed ever made?).

Historical and Development models

These are unlikely to be readily available, and would then be in demand by collectors.

Raspberry Pi 1st Production Board

  • Announced: 29th Feb 2012 - Start of Sale Only[6]
  • Credit-card Format
  • Initial 10k Batch (All Model B's) Manufactured in China (Jan/Feb 2012)[7]
  • Should look identical to the Raspberry Pi Beta Board below (except different SDCard holder).
  • The board has a yellow RCA connector, rather than the black one used in the Beta's.
  • Nokia/Qt Development group has donated vouchers for 400 RPi units for developers[8]
  • The batch was delayed several weeks due to the RJ45 network connector being substituted for the wrong part[9] and also so the board could undergo compliance testing[10]

Raspberry Pi Beta Production Board

  • Announced: December 2011[11]
  • Credit-Card Format
  • Manufactured in UK
  • Produced 100[12] PCBs
  • Characteristic feature of hand-modded correction to PCB [13]
  • See the blog post which includes a video explaining how the production units will differ from the beta boards.

Official Camera

The foundation sells a handful of different cameras. Identifying the one in use via software can be done by first identifying which device it is. Usually it will be /dev/video0 however the presence of USB cameras will change this.

v4l2-ctl --list-devices

This will list a number of devices (not all of them are video devices, some are used for hardware accelerated video encoding and decoding). Look for one that has platform:bcm2835-v4l2 in the name, like this:

mmal service 16.1 (platform:bcm2835-v4l2-0):
        /dev/video2

This shows the Pi camera is located at /dev/video2.

Next, query the device for supported resolutions. This uses the default /dev/video0 so change if needed.

v4l2-ctl -d /dev/video0 --list-formats-ext

A list of video capture formats will be shown. Look for the largest capture resolution. For example, there may be an entry like this:

  [0]: 'YU12' (Planar YUV 4:2:0)
    Size: Stepwise 32x32 - 2592x1944 with step 2/2

This indicates that the largest frame size is 2592x1944 which matches a version 1.x camera. The full list of resolutions is available in the official docs, but in summary:

Camera model Maximum resolution
1.x 2592x1944
2.x 3280x2464
HQ camera 4056x3040
