From the project

Replacement board for Casio Calculator Watches using the CC430F6147

These directories contain different hardware revisions of the GoodWatch. When a revision is manufactured, its files are copied to a new directory and the old may only be updated for documentation reasons.

The GoodWatch 22 and earlier were designed in Kicad 4, and might be awkward to open in newer revisions. The GoodWatch30 is designed in Kicad 5.

This is our current design, featuring a new balun and more generous filters. Email Travis for some free PCBs if you'd like to build one.
