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.

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
 * 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
 * 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.

eBay Auction
10 of the completed Model-B boards were auctioned on eBay (Started on 1st Jan 2012) ) Board #7 was anonymously (and generously) donated to Centre for Computing History (also spotted here..)!

Board #8 Owned by Tech Blogger, Paul Maunders, see his blog for details

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.


 * Alpha prototype board, underside

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
 * Introduced the RPi Foundation to the world (any earlier links appreciated), featured by BBC Online Video.
