DYS F4: Connecting Sbus Receiver & Telemetry

To be able to use Sbus and get telemetry with the DYS F4 flight controller there are some things you have to know.
1. Do not use Betaflight 3.1.7 firmware because the hardware inverter does not work.
2. UART 3 Tx and Rx pins are backwards from the wiring diagram
3. Although UART 1 has the hardware inverter that will make Sbus work, you still have to invert the telemetry signal from FrSky receivers to make telemetry work by doing a hardware modification.

If you have a PPM receiver like the D4R-II then watch this video -
If you use a Turnigy transmitter then I recommend I-bus instead of Sbus. Watch this video -
