How to wire the A/T disengage and auto take off and go around buttons? They are not listed on the wiring diagram and also no extra spots on the leobodnar for them?

Hi Karl

Just looking at the micro pro wiring diagram, can you power the parking brake light from this board or do you have to have the mega board as well. Basically trying to just use one board in the throttle unit with one usb lead coming out?

Hi Steve I've been wondering the same thing and have come across the following page which would indicate it is possible.

I think if you edit the Joystick Library sketch with the code from above then it will possibly work?

Another option may be to bypass the need for it to go through the card altogether. Just take the 5v off the board and make a circuit between the Parking Brake micro switch and the LED.

@David Cram that's my plan to just wire the LED switch i found directly to the parking switch, replace the LED for smaller and add some resistors.
