Arduino Dev Board, Atmega32U4, Arduino Leonardo R3, No Headers - A000052

Arduino Dev Board, Atmega32U4, Arduino Leonardo R3, No Headers - A000052 Product Overview

The Arduino Leonardo is a microcontroller board based on the ATmega32u4
(datasheet). It has 20 digital input/output pins (of which 7 can be used as
PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB
connection, a power jack, an ICSP header, and a reset button. It contains
everything needed to support the microcontroller; simply connect it to a
computer with a USB cable or power it with a AC-to-DC adapter or battery to
get started. 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.
