I am considering adding tac switches for the d-pad on my CM3 board. To do this I am thinking of drilling small holes around the pads for the dpad to secure and wire the tac switches to. Does anyone know if the PCB is multi layered? I would hate to break a trace in the middle of the board that I can't see. Additionally, does anyone know if the pads for the d-pads are wired straight to the sodimm socket or do they run through any IC's or resistors? If so that might be an alternative instead of drilling. I apologize if there is a published schematic for the PCB that I could look at to find this info, I looked around but couldn't find one. Thanks.
