Description

The BMT Leonardo R3 is a powerful and cost-effective microcontroller board compatible with Arduino Leonardo. Based on the ATmega32u4 chip, it integrates built-in USB communication, eliminating the need for an external USB-to-serial adapter. This allows the board to appear as a keyboard, mouse, or virtual COM port, making it ideal for projects requiring direct USB interaction.

Equipped with 20 digital I/O pins (7 PWM outputs and 12 analog inputs), the Leonardo R3 offers flexibility for a wide range of electronics projects, from robotics and automation to IoT and prototyping. It also features a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button.

With 32KB of flash memory, 2.5KB SRAM, and 1KB EEPROM, the board provides ample storage for code and applications. Its 5V operating voltage, wide input range (7-12V recommended), and compact size make it easy to integrate into both hobbyist and professional designs.

This board comes with a USB cable included, so you can start programming and testing immediately using the Arduino IDE.
