I'm starting an accessory development project and want to make sure I'm purchasing the right thing. The example source code I have is based upon the Google ADK 2011 reference design. There is a 2012 reference design as well (http://developer.android.com/tools/adk/adk2.html
). I've noticed the schematics for the Google reference ADK 2011 and the Mouser part number 782-A000069 are different, and the latter is listed as "Rev 3". Can anybody tell me the differences between these two designs? I could carefully go through the schematics but I'm afraid I might miss something important. Thx.
