UART Info:

  • UART1: Receiver (FrSky, Spektrum, Crossfire, etc).
  • UART3: SmartAudio (or any other desired output if SmartAudio is selected to pull signal from the “external” pad, designated RX SA on the top of the FC).
  • UART6: ESC Telemetry (if applicable).




Pit mode “mode” selection in the modes tab will be used to control the vtx.  The above CLI commands set the mode switch to control the pin output instead of sending a command to the VTX to go to the “graveyard” channel.

        Before: Pit Mode - command VTX to go to its assigned graveyard channel via SmartAudio.

        After: Pit Mode - controls output of Pin B15 to output a “HIGH” or “LOW” command which controls the power that the VTX receives.
