DATASHEET

Main Features

The UNO Mini Limited Edition (LE) is a miniature version of the classic Arduino UNO board. It is based on the ATmega328P microcontroller, has USB-C® connector for programming and powering the board, and pins available for connecting external power sources. It also comes with the standard set of female pin connectors, built-in LED, reset button and everything else that the standard UNO have, but at 25% the area size!.

Tiny Form Factor

The UNO Mini LE is roughly 25% the area size of the classic UNO board (but equally as powerful).

Documentation

Pin Header Pitch

The pitch (distance between pin holes) is 0.05", or 1.27 mm. This is half the distance compared to the classic, regular sized UNO (0.1", 2.54 mm).
