It’s an interesting and hard process to discover the different ways of boards.
We tried to design an Arduino(TM) compatible board fits to smallest apertures. The goal is extremely small, slim, flexible while maintaining its nature of developing board.
Cut-able, Scrollable and Chain-able
Full functional Atmega168/328 breakout
Built-in charger circuit
Default a complete Arduino compatible board, could be cut to fit needs
20pin bus passed across all blocks
light, slim, small, flexible as planned
Too slim to fit in the connectors
Might still be too much overhead
It is far from mature, we will prepare a few prototypes for community inspiration. Please let us know how you might use them and the key factors you would care, we will select the comments and ship them in one week frame. Thanks!
