It is a kensington expert mouse, it's a trackball but uses the same components/technology as regular mice, just a different layout to accomodate the different design e.g. buttons or a scroll ring.
I have an older trackball mouse that has a better sensor (starts jittering instead, but the "max tracking speed" is much higher, so I would REALLY have to spin the ball to get it to screw up), but is worse in every other way. So I was just wondering if I could just replace the sensors between the two mice? Would that work? Or is it a firmware issue? In which case I have some debugging experience, is there a way to increase the threshhold?
Also, I've noticed that the two sensors are extremely similiar, just slight differences in some parts having corners instead of edges, so I am not too sure if this would make a difference in replacing them.

I am open to swapping the PCB, but I have no idea where I would even get replacement parts for that. The mouse case is pretty big and sparse, so I think I have good leway with what I can put in it. Is there some place I could buy good PCB parts for mice and be able to customise the button layout? Or maybe a website that can print mice PCBs + button layout?
Also, is there perhaps a way to change the "max tracking speed" in the firmware?
