    Arduino Leonardo R3 (Clone)


    The Arduino Leonardo R3 is a microcontroller board based on the ATmega32u4 chip. It is a clone of the original Arduino Leonardo and is designed to be similar in functionality. This board has 20 digital input/output pins, 7 PWM outputs, and 12 analog inputs, as well as a 16 MHz quartz crystal and a micro USB connection for programming and power. The Leonardo R3 is unique compared to other Arduino boards in that it can emulate a USB keyboard and mouse, making it useful for projects that require human-computer interaction. This is a cost-effective alternative to the original Arduino Leonardo.
