Only with a Atmega32u4 USB communication and control. The Leonardo differs from all preceding boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial \/ COM port. It also has other implications for the behavior of the board. Greatly improve the applications.
