Use this issue to track the PCB manufacturing and initial assembly. Close when the design is complete and we move on to the '11 or '20.

The bottom slot cut interferes with through hole plating. I'll send the PCB manufacturer an updated Gerber.

Updated designs have been pushed to the repo and sent to the manufacturer.

The first batch of 141 PCBs have shipped from Wuhan, to arrive on Monday.

Boards have arrived. If you see me cussing on Twitter this evening, it's because of those 0201 capacitors.

Layout errata:

(Check when fixed in GoodWatch11 layout.)

[ ] Corners need to be rounded to fit within plastic tray.
[ ] 0201 is awful to solder by hand; grow to at least 0402, maybe 0603.
[ ] Unused pins really need to go somewhere, to avoid lifted pads.
[ ] Drill holes are too small for the Casio plastic.
[ ] R1 is unnecessary, thanks to an internal pull-up. Cut it to save traces.
[ ] The 32kHz xtal needs to move slightly North to fit the plastics.
