Board Revision History

Find out your board revision with 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).

ECN0001

ECN0001 is the request to not fit D14 and replace 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

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].

Raspberry Pi Model-A Full Production Board

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

Raspberry Pi Model-B Full Production Board

The Rpi full production board (model B Rev 2.0)

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.



eBay Auction

10 of the completed Model-B boards were auctioned on eBay (Started on 1st Jan 2012) [14])
