Trackball requires a trackball sensor breakout board. I have my own breakout board that I offer, but I also tested with the charybdis sensor pcb ( https://github.com/Bastardkb/charybdis-pmw-3360-sensor-pcb )

soldering of two Charybdis Trackball PCBs (I don't think I can convince u/FMcraft to sell me two assembled ones solo without a whole kit).

Unfortunately yes. I'm going to remove the sensor breakout board and try it with a different mcu just in case, but I highly suspect that my sensor (or the breakout board is at fault.

At the same time (when it's ready... still have to do build guides and finish firmware) I will open source the 3d files like on the rest of m designs. The whole thing is made to be handwired, but does require a few PCBs to make your life easier: a custom PMW3360 sensor PCB, and an elite-C shield including a connector for the sensor PCB.

By the way I had time to test the PCB - works well. Here's a link to the github https://github.com/Bastardkb/charybdis-pmw-3360-sensor-pcb

On top of the case, tents and plates, there is also a 3d printed adapter that screws in and holds the ball, bearings, and PCB. It's designed to be reused in other keyboards if you want to make your own 34mm trackball keyboard.
