Arduino Leonardo Microcontroller
We have ✅ 11 available of the DF-DFR0201 in our Sydney warehouse. An extra 9 units available with a short lead time.
The Arduino Leonardo is a microcontroller board based on the ATmega32U4, offering the same flash, RAM, and capabilities as the ATmega328 found in the Uno. The key difference is built-in USB communication, allowing the Leonardo to appear as a keyboard, mouse, or serial device to a connected computer — no secondary USB chip required.
With 20 digital I/O pins, 12 analog inputs, 7 PWM channels, and a micro USB connection, the Leonardo is ready for interactive projects straight out of the box. This version comes with all headers pre-soldered for easy breadboard and shield use.
Key Features
- Native USB – Built-in USB on the ATmega32U4 enables keyboard, mouse, and serial device emulation
