The Leonardo R3 Board, Micro-USB compatible with Arduino, is powered by the ATmega32u4 microcontroller. Featuring 20 digital input/output pins (7 PWM outputs, 12 analog inputs), a 16 MHz crystal oscillator, micro USB connection, power jack, ICSP header, and a reset button, it’s an all-in-one solution for your projects.
With built-in USB communication, the Leonardo R3 differs from its predecessors as it doesn’t require an additional processor. Simply connect it to your computer via USB or power it using an AC-to-DC adapter or battery to start your projects.
The ATmega32u4’s unique feature allows the Leonardo to emulate a mouse and keyboard, in addition to serving as a virtual serial/COM port. This opens up various possibilities for creative applications and unique board behavior.
