    Remember:

    • Use UART3 for the receiver. Only this port has an inverter that is needed for S.Bus. Power the receiver from the 5V output on the serial (UART1) port
    • UART6 TX can be used for FrSky SmartPort telemetry. Only this port has the necessary signal inverter.
    • If you want to use SmartAudio to configure your video transmitter, use the UART1 TX pad for this functionality
