Compared to other versions of the use of a separate USB-to-serial converter chip, the Leonardo innovatively uses a single-chip solution. Only with Atmega32u4 USB communication and control. The Leonardo differs from all previous boards in that the ATmega32u4 has integrated USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear on a connected computer as a mouse and keyboard, in addition to a virtual serial / COM port (CDC). This also has other implications for the behavior of the board. Significantly improve applications. Leonardo requires the new version above IDE1.01.
