2022-03-03 (Th) RemoteFinishLine Second unit soldered

My prototype worked well enough as a single-point start/stop line, and since my IO worked, I started building the second breakout board. I had the first to copy, which worked most of the time, but I confused myself a few times by misplacing the button. I improved the design by installing a couple of header pins behind the switch instead of adding double-length posts to the sockets, which you can see in the picture. I also marked the populated sockets with a white Sharpie, so I don't have to guess when I attach modules later.
