KeyDuino - The quick & easy way to build NFC enabled things. The KeyDuino development board is Arduino compatible hardware and software.Since the KeyDuino is based on the Arduino Leonardo (ATMEGA32U4) anything that runs on an Arduino Leonardo will also run on a KeyDuino and this means whatever shield (with a few exceptions) work with an Arduino will also work with KeyDuino.
