Hardware & Peripherals:

Hardware - detailed information about the Raspberry Pi boards.

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.

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 [1].


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).

Raspberry Pi Model-A Full Production Board

  • Announced: Not Yet (as of 16 June 2012)
  • Board will now have 256Mb of RAM rather than the originally planned 128Mb[3]
  • Foundation will probably produce a small Beta batch before handing manufacturing over to RS and Farnell

Raspberry Pi Model-B Full Production Board

The Rpi full production board (model B)

Raspberry Pi 1st Production Board

  • Announced: 29th Feb 2012 - Start of Sale Only[3]
  • Credit-card Format
  • Initial 10k Batch (All Model-B's) Manufactured in China (Jan/Feb 2012)[4]
  • 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[5]
  • The batch was delayed several weeks due to the RJ45 network connector being substituted for the wrong part[6] and also so the board could undergo compliance testing[7]

Raspberry Pi Beta Production Board

The Rpi beta board (model B)
  • Announced: December 2011[8]
  • Credit-Card Format
  • Manufactured in UK
  • Produced 100[9] PCBs
  • Characteristic feature of hand-modded correction to PCB [10]
  • 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) [11])
