The initial schematic and PCB routing are done for the Hackpad. I decided to try and make it wireless to add some complexity to the project, so I am using a Xiao nRF52840 instead. I also added hotswap sockets instead of the solder sockets so I could test different switches. I also went with two encoders for more inputs. The setup should also work with the default RP2040; however, the left encoder will not work. Next up is designing the case for it.
