MSP430Watch2 – Barometer and Wifi (PCB Design)



A long while ago, I played with an hacked together watch, based on the msp430. Recently I’ve been playing with a few interesting parts, the esp8266, an interesting I2C LCD and a cheap barometric sensor.

I decided to throw all these components together in a watch layout, just for fun! The PCBs are now out to fab and I’ll update this post when I’ve built everything up. I’m not sure I’ll actually place the esp8266 and if I do, for any kind of sensible power consumption it would need to be off most of the time.

The schematic is below, and you can also find everything on github here.

Other footprints are from the Kicad libraries.
