Here's what the inside of the Polyend Tracker looks like. It runs on an ARM Cortex M4F design from NXP.
@tindall ah wow, thanks for the detailed shots :0
I didn't realize that the polyend was using cherry mx style keys... and are the buttons basically adafruit trellis pads?
@jonbro absolutely! I love taking stuff apart :) for science, of course.
The Trellis grids are squishier, I think. These are relatively hard, and not pressure sensitive.
