UNO Mini Limited Edition

The Arduino UNO Mini Limited Edition (LE) is a unique black & gold board, that pays tribute to everyone's favorite maker board: the Arduino UNO. It is only 25% of the area size of the original UNO, comes with a USB-C® connector and is delivered in a special case.

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!.

UNO Form Factor
Tiny Form Factor

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

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).
