Dann könntest Du das LED Pad ummappen.
Wie das geht steht z.B.
hier.
Allerdings bin ich mir nicht sicher, ob das für WS funktioniert, da es einige Einschränkungen gibt:
When using Softserial, please note the following:
- Softserial should not be used above 19200 baud (not possible in Betaflight 4.5)
- Softserial should not be used for MSP connections such as HD OSDs (not possible in Betaflight 4.5)
- Softserial may not work with some serial devices.
- Only two Softserial UARTs may be used at any one time.
- The baud rate on all Softserial ports must be the same.
- It is always better to use a hardware UART if one is available
