Arduino Nano vs Arduino Leonardo

We compare these two popular Arduino boards to help you choose the best option for your project.

Arduino Nano

ATmega328

Compact version of Arduino Uno with the same microcontroller but in a much smaller format. Ideal for projects where space is limited and portability is needed.

Arduino Leonardo

ATmega32U4

Arduino with integrated native USB that allows it to act as an HID device (keyboard, mouse). Ideal for human interface projects and computer control.
