I just recently received my Sensor Watch pcb that I ordered from crowdsupply a little while back. The pcb is a drop in replacement for the Casio F91-W wrist watch that provides GPIO expansion for sensors and a Cortex M0+ processor for custom firmware. After installing it in my F-91W I take a quick look at it and give my thoughts.
