Arduino Leonardo Description
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 connector, a power jack, an ICSP header, and a reset button. It includes everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.
The Leonardo differs from all previous boards in that the ATmega32u4 has built-in USB communications, 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; these are detailed on the getting started page .
Getting started with the Arduino Leonardo
In the Getting Started section you can find all the information you need to configure your board, use the Arduino Software (IDE), and start tinkering with coding and electronics.
