I started working on the PCB! I had previously tried out kicad as part of a mini keyboard project, but it turned out rather difficult to work with, and for some reason alignment wasn’t working at the time, so I gave up. But this time, alignment seemed to just work, components aligned to a shared global grid, and so it worked out overall. I’m quite happy with how it turned out; nothing crazy, with the addition of only an LED, but hopefully it should be functional!
