Maker Faire in New York on 29th September 2012: Image from: <[youtube 4TZQt9lTAOU]>
Sorry image is a bit grotty. There are better pics on web but they aren’t identical to this one which is “official”. After a year since it was announced let’s hope it was/is worth waiting for.
a) two USB ports – one conventional Arduino for serial port + optional power. The other can be master or slave.
b) probably Atmel SAM3X8E processor – I do wonder whether this is optimistic or implies the Arduino Due will be relatively expensive – but he said $49.
c) The simple Arduino IDE upgraded and apparently generalised to make addition new boards / chips easier
