Watch Board prototype has arrived
Watch Board has arrived the other day, and it looks great. I ordered 3 for prototyping and testing the electronics. All the parts are in except for one. Sadly it's the much needed stencil for surface mount assembly. The bluetooth IC is 0.5mm pitch spacing so I gave up trying to put solder paste on each pin.
Look forward to assembling the electronics next week.
