As I finished wiring the matrix of my 3x3 MacroPad, I realised that the HackPad microcontroller did not have enough pins to accommodate this. I then realised that my LCD screen is also wired to the wrong pin so I decided to take out the bottom three keys. Now I should have enough space to run my VCC, SCL, and SDA ports for the screen. I’m a little frustrated with myself for not realising this earlier. It would have saved a lot of time but I’m glad I caught it before I sent this PCB off.
