Arduino Leonardo R3 Board Clone Model

Arduino Leonardo R3 Board Clone Model

The Arduino Leonardo R3 is a powerful and versatile microcontroller board based on the ATmega32U4 chip. Unlike most Arduino boards, the Leonardo features built-in USB communication, allowing it to emulate a mouse, keyboard, or other HID (Human Interface Device) directly through its USB interface.

This clone model offers full compatibility with the original Arduino Leonardo, delivering the same performance and reliability at a more affordable cost. It’s an excellent choice for USB-based projects, input devices, and custom HID controllers.
