If you’re new to pcb design, I’d recommend learning KiCad! I haven’t designed a keeb pcb in a few years so my skills are rusty, but I learned the basics with this series on youtube called ‘getting to blinky’. There may be better or more up to date ones available these days, though. I’d maybe just take one of the side macro pads and just make that as a standalone to get the hang of it first before going hog wild with the whole thing. Honestly though, despite how tedious it is, handwiring a matrix isn’t too too bad!
Bummer! I wonder if the clock just has a bad crystal. Maybe the solution is to instead use the gif mode to display something fun.
