Arduino Leonardo low profile

New Arduino family member - Arduino Leonardo. Based on ATmega32U4 has USB support on chip, thus Serial port used to communicate with computer becomes virtual one - UART on digital pins 0/1 is free to other uses!

This board is compatible with Arduino UNO (Arduino IDE 1.0.1 is required to get support for this board). It uses micro USB connector on board.

Good writeup with differences between Leonardo and UNO can be found on Arduino wiki.

Low profile

This board is a bit different from basic Arduino Leonardo: there is no high parts on boards (ICSP connector, sockets, power jack) thus whole board has 5 mm in highest place (reset switch). Not counting reset button and micro USB connector outside of board edges, height is only 4 mm (including PCB).
