Arduino Leonardo - Bitesize Review - A000057

Paynetech provide maker spares and support for the UK; We've made this series of review videos to give you a quick and easy way to determine which Arduino board is right for your project.

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.

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.
