Leonardo R3 Board

The Leonardo R3 is an advanced development board based on the ATmega32u4 microcontroller, offering built-in USB communication. Unlike other Arduino boards, the Leonardo can emulate a keyboard, mouse, or joystick, making it ideal for HID (Human Interface Device) projects and interactive systems.

This board includes 20 digital I/O pins (7 PWM outputs and 12 analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It’s fully compatible with Arduino IDE and great for custom computer interfaces, automation tools, and educational purposes.

Key Features:

• Microcontroller: ATmega32u4

• Operating Voltage: 5V

• Input Voltage: 7-12V

• Digital I/O Pins: 20 (7 PWM)

• Analog Input Pins: 12

• USB Interface: Native USB (no FTDI chip)

• Micro USB port for programming

• Ideal for HID projects like custom keyboards and game controllers

Take control of your PC or Mac like never before with the Leonardo R3 – your gateway to creative USB-based applications.
