Description

Leonardo R3 Micro-USB Development Board (Compatible with Arduino)

The Leonardo R3 Micro-USB Development Board is a microcontroller board based on the ATmega32U4. Unlike earlier Arduino boards, the ATmega32U4 features built-in USB communication, eliminating the need for a separate USB-to-serial processor.

This board provides 20 digital I/O pins (including 7 PWM outputs) and 12 analog input pins, making it suitable for advanced input/output applications. It includes a 16 MHz crystal oscillator, Micro-USB connector, DC power jack, ICSP header, and a reset button.

Simply connect the board to a computer using a USB cable, or power it via an external adapter or battery, and you’re ready to start developing projects using the Arduino IDE.
