Arduino Leonardo


The Arduino Leonardo differs from its predecessors in that the featured ATmega32u4 MCU has built-in USB communication, eliminating the need for a secondary processor. As a result, the board is able to implement protocols beyond the USB to serial protocol. The Leonardo can therefore appear as a mouse or keyboard to a connected computer, for example.
