When the Revolution flight controller is plugged into the GCS, the Hardware Configuration screen displays the ports available on the controller to allow them to be set according to use. The board can be mounted in any configuration on the airframe, and the orientation relative to the airframe configured such that the flight controller knows which way it is facing.

Flexi Port

Can be disabled, or connected to one of the following: GPS, Telemetry, I2C, OsdHk, DSM, SRXL or a Debug Console.

Main Port

Can also be left disabled, or connected to telemetry, GPS, S.Bus, DSM or a Debug Console.

With DSM, this means the flight controller can work directly with a Spektrum satellite receiver.
