James, the TQ has a PCB as does the PT. They are seperate. The PT PCB is in the handle and the TQ one I added into the base. Using both PCBs gives the user the best of both worlds, a PT/TQ so to speak. This does require the two USBs. If I could fit 4 more axis in the PT, with the TQ PCB it would be possible. The CH PCBs are available, in their items, FS, CS, PT,... well, you get the picture. As for the wiring diagrams, I figured it out looking at the circuit board the TQs POTs are mounted to.
