Board Revision History
Find out your board revision with the following command:
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 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 is the request to not fit D14 and replace F1 and F2 with 0 ohm.
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.
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 .
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 PCB, and RS Components produced a limited edition of anniversary Pis in Blue.
Raspberry Pi 2 Model B
Announced on 2nd Feb 2015 Full announcement from the Raspberry Pi Foundation.
The Raspberry Pi 2 features a Broadcom BCM2836 SoC, with a quad-core ARM Cortex-A7 CPU and a VideoCore IV dual-core GPU; 1 GB of RAM with remaining specifications being similar to those of the previous generation model B+. The Raspberry Pi 2 retains the same US$35 price point of the model B+.
Raspberry Pi Model-B+ Full Production Board
Announced on 14th July 2014 Full announcement from the Raspberry Pi Foundation
Raspberry Pi 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 512Mbyte of RAM) as well as a 4Gbyte 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 256Mb of RAM rather than the originally planned 128Mb
- 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
- 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).
- Announced: September 2012, Raspberry Pi Model B Rev 2.0 is now manufactured at Sony's manufacturing plant on Pencoed, South Wales. Full announcement from the Raspberry Pi Foundation, Element14 announcement on Raspberry Pi discussion board.
Raspberry Pi 1st Production Board
- Announced: 29th Feb 2012 - Start of Sale Only
- Credit-card Format
- Initial 10k Batch (All Model-B's) Manufactured in China (Jan/Feb 2012)
- 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
- The batch was delayed several weeks due to the RJ45 network connector being substituted for the wrong part and also so the board could undergo compliance testing
Raspberry Pi Beta Production Board
- Announced: December 2011
- Credit-Card Format
- Manufactured in UK
- Produced 100 PCBs
- Characteristic feature of hand-modded correction to PCB 
- 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
10 of the completed Model-B boards were auctioned on eBay (Started on 1st Jan 2012) )
Raspberry Pi Alpha Board
- Announced: August 2011
- 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
- The "Computer On A USB Stick" Format
- Included built-in camera
- HDMI one end and single USB the other
