Arduino Leonardo R3

Description

The Arduino Leonardo R3 is a powerful microcontroller board based on the ATmega32u4, designed for a variety of electronics and embedded projects. Equipped with 20 digital input/output pins, including 7 PWM channels and 12 analog inputs, it offers flexible interfacing options for sensors, actuators, and other peripherals. The Arduino Leonardo R3 operates at 16 MHz and 5V, making it ideal for numerous applications requiring precision and real-time control.

One of the standout features of the Arduino Leonardo R3 is its built-in USB communication capability. Unlike other boards, the ATmega32u4 directly handles USB communication without requiring a secondary processor. This allows the board to emulate USB devices like keyboards, mice, or a virtual COM port, making it incredibly versatile for custom input device development. The Arduino Leonardo R3 also supports programming via a micro-USB connection, making it easy to upload sketches and power the board simultaneously.

Compact and lightweight, the Arduino Leonardo R3 is perfect for both beginners and advanced developers. Whether you’re creating custom game controllers, automation systems, or robotics projects, this board provides the functionality and ease of use to bring your ideas to life.
