Not familiar with how keyboard PCBs work entirely, but how does that work as a macropad without needing wires to bridge some of the traces to complete the circuit?

The keyboard is just a matrix of rows and columns. So I just lopped off a bunch of each making the matrix smaller but still operational.

Still not sure I understand but neat to hear. I gotta learn how to do PCB design so I can make my own keebs

Wanted to make a macro pad as a Christmas present.. didn't have any controllers, but I do have a few spare PCBs for a 75 key ortho I made.
I'm so sorry.
