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.
