split-kbd
Its gonna have thumb clusters and stuff. It's gonna use the same dev board as the guide, but it'll also have an io expander since XIAOs have basically zero IO.

Routed the PCB
I routed the PCB both left and right. I also put it in the JLCPCB and PCBWay Gerber viewers to check that I did the edgecuts right (specifically mousebites).

Finished laying out the right side
The right side is now layed out. I did it manually, so its slightly different compared to the left side. but its fine because the edge cuts are the same.

Made schematic and layed out left part of PCB
I made a schematic and PCB. I had to use an IO expander since i wanted a 6x7 grid (67). The bottom row was transformed into a thumb cluster. Wiring that will not be fun. I've partially layed out the right part of the PCB, but I'm not very confident in my mousebites.
