Today I was able to design the PCB for CloudPad, a nine-key macropad that will be able to open up my favorite apps with ease. Rather than using a pin on the board per key, I opted to use a diode matrix, which is something I’ve never done before. In the end, I think the PCB came out looking well, though I am worried that the board won’t come out perfectly square as I wanted, so maybe I’ll make some revisions later.
