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.
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
Newest revision at the top of the list.
Release Date | Model A/B | PCB Revision | Build Revision | Notes |
---|---|---|---|---|
N/A | A | 1.0 | None | ECN0001 |
Q3 2012 | B | 1.0 | 0003 | ECN0001 |
N/A | A | 1.0 | None | |
Q1 2012 | B | 1.0 | 0002 | |
Q1 2012 | B | Beta | Beta | Beta Board |
- The model A's do not have a board revision number, as they are not released at present
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.[1]
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[2]
- Foundation will probably produce a small Beta batch before handing manufacturing over to RS and Farnell
Raspberry Pi Model-B Full Production Board
- Announced: April 2012, first orders sent out June 2012.
- Manufacturing and Orders will be made through RS and Farnell
- This means a much higher volume of units will be produced and made available.
- Additional detail is available about the manufacturing and distribution agreement here video interview between Eben Upton and SlashDot here (28/02/12).
Raspberry Pi 1st Production Board
- Announced: 29th Feb 2012 - Start of Sale Only[2]
- Credit-card Format
- Initial 10k Batch (All Model-B's) Manufactured in China (Jan/Feb 2012)[3]
- 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[4]
- The batch was delayed several weeks due to the RJ45 network connector being substituted for the wrong part[5] and also so the board could undergo compliance testing[6]
Raspberry Pi Beta Production Board
- Announced: December 2011[7]
- Credit-Card Format
- Manufactured in UK
- Produced 100[8] PCBs
- Characteristic feature of hand-modded correction to PCB [9]
- See the blog post which includes a video explaining how the production units will differ from the beta boards.
- Pre-production board (beta board) PCB, topside
- Pre-production board (beta board) PCB, underside
- Pre-production board vs credit-card
eBay Auction
10 of the completed Model-B boards were auctioned on eBay (Started on 1st Jan 2012) [10])

Raspberry Pi Alpha Board
- Announced: August 2011[13]
- Large Format for debugging (Model-B)
- Populated with headers for GPIO, JTAG, DSI, CSI, as well as switches and LEDs for I/O testing.
Raspberry Pi USB Prototype Board
- Announced: May 2011
