We are looking for a circuit board diagram for the F310 controller. We have one we want to disassemble and utilized the board to build a custom controller. Not having any luck locating one. Our primary concern is that we don’t want to wire the potentiometer in backwards where we are disconnecting the current analog sticks.
Unfortunately I don’t have any information on the Logitech controller, but do you have your heart set on using board from the F310? There may be some better options out there if you want to build a custom controller, that would be easier to implement.
The one that comes to mind is Andymark’s new product (it doesn’t come with an analog stick, but maybe you can add one):
