Will we theoretically be able to design a keyboard with this component? I wish I could just get one I can insert onto a breadboard but these i2c devices seem to only be for PCB boards which means that I would need a development board for it. Once I got that I can test a circuit setup on the ATmega328PB and/or on a Raspberry Pi.
There is a kernel driver for the TCA8418 and I have used it with the Raspberry Pi. This chip should work just fine with the PinePhone. My dts overlays used for the raspi are at https://mozzwald.com/raspi/ and there is a spreadsheet there I used to help figure out my matrix for the dts.
I have a QFN24 breakout board available on OSH Park that you can put the TCA8418 on and use it with a breadboard.
