japanino

Last update: Sat Jan 10 23:04:54 2026

I'm the happy owner of a rare Japanino.

Presentation

A small minor Japanese board, clone of Arduino, and that I bought years ago to support Japan industry.

Points of interrest

Well it's a rare Arduino clone, with a atmega168 and a 8MHz crystal, and a CP210x USB to UART Bridge.

Implementation

Integration in Arduino IDE
