Arduino Leonardo Development Board

Description

The Arduino Leonardo Development Board is powered by the ATmega32u4 microcontroller, which features native USB support. Unlike other Arduino boards that use a separate USB-to-serial converter, the Leonardo communicates directly over USB, allowing it to emulate human interface devices (HID) such as keyboards and mice.

This capability makes the Arduino Leonardo especially suitable for USB-based automation, custom controllers, gaming interfaces, and security research projects. Fully compatible with the Arduino IDE, it supports a wide range of libraries and shields, making it easy to integrate into both beginner and advanced electronics projects.
