Leonardo R3 development board Board + USB Cable ATMEGA32U4 For Arduino
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.
Description
The Arduino Leonardo board use an ATmega32U4 to offer you more functionalities compared to Uno.
The Leonardo is programmed using the Arduino Software (IDE), Integrated Development Environment common to boards and running both online and offline. For more information on how to get started with the Arduino Software visit the Getting Started page.
Main Features
The Arduino Leonardo is a microcontroller board based on the ATmega32u4. 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.
