Quarter size stackable Arduino

Tiny circuits have introduces really small Arduino board. It’s even smaller than a quarter coin. On a circle shaped PCB there is Atmega328P microcontroller in MLF package. On the edge you can find reset switch, status Led and battery connector. Due to size constraints USB connectivity and ISP is implemented in external tiny shield. These shields can be stacked one on another using special miniature connector.

Modular structure allows to achieve small sized applications that may fit in to small robots, rocket models or in any tight space. There are already several shields available – USB & ISP, 16 LED and bunch pr prototyping shields. They also come in 20mm square shape. Be sure to check out TinyLily as well.
