The board contains everything required to support the microcontroller. Simply connect it to a computer using a USB cable or power it using an AC-to-DC adapter or battery to get started.
Unlike earlier Arduino boards, the Leonardo uses the ATmega32u4 with built-in USB communication, eliminating the need for a separate USB-to-Serial processor. This allows the board to appear to a connected computer as a keyboard, mouse, or virtual (CDC) serial device.
