• Leonardo Arduino Compatible ATmega32u4

If you know Arduino's you know that it is an open sourced hardware device. This means that reference files and designs are freely provided. This means that high quality boards can be made to the exact same parts, quality, functionality, and compatibility as the official released boards. This is one of those boards 100% compatible with the Arduino IDE and built with the same parts and quality.

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.
