The 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. It also has other implications for the behavior of the board; these are detailed on the getting started page.

This generic model is completely compatible with the genuine Arduino® Leonardo. We also stock the genuine made in Italy version.

Programming

The Leonardo can be programmed with the Arduino® software (download). Select "Arduino® Leonardo from the Tools > Board menu (according to the microcontroller on your board). For details, see the reference and tutorials.

The ATmega32U4 on the Arduino Leonardo comes preburned with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. It communicates using the AVR109 protocol.

You can also bypass the bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) header; see these instructions for details.

    I was a bit dubious buying this because of how cheap it is compared to the official board. But my concerns were allayed as soon as I took it out of the box. The boards performs perfectly and doesn't miss a beat. (Posted on 30/09/2013)
