Spent two untracked hours begining working before realizing that Hackatime was not linked and fixing that issue (tutorial). Found a different guide to making mechanical keyboard PCBs with KiCAD that was way easier to follow and got this made! I am not sure how close the edge of the PCB should be to the USB-C port on the XIAO, so I may adjust that later. Other than that, I think the PCB is finished!
