I'm sure Mike Copioli will get on here and give you a full rundown, but from what I've gathered from our use:
-Plugs into the FRC Operator Interface (not VEX, sorry)
-Supports a variety of USB controllers, joysticks, a Racing Wheel and a Mouse (
full list here) including the Xbox 360 USB controller
-Requires power from a 7.2V backup battery in competition (separate from rest of controls)
-This requires a 7.2V backup battery and adapter (Both available at IFI)
-Can use 7.2V AC Adapter outside of competition to run. (Also available at IFI)
