Thanks to the published CAD files, I figured out how to fix the buttons on my @sqfmi Watchy.
Some vias are corroded due to moisture, most likely from rain. In theory, all I have to do is solder two little jumper wires 🟠 🔵 without dislodging any other components. Those pads are 1 mm. 😬
Wish me luck. 🤞
