Note: When you connect the receiver to 2s fc, please don't forget to plug the battery, otherwise the reciver will not

work at all because if you don't plug the battery, the reciver doesn't have any power to work.

Receiver Connection

1) How to connect a receiver with SBUS signal output (Frsky XM+ (https://betafpv.com/collections/rx-tx/products/frsky-xm-

sbus-mini-receiver) for example).

Here is the connection diagram with XM+ receiver.

We use the AUX12 channel as the RSSI signal channel in XM+ receiver.

Step 1, on Betaflight GUI, configure the UART1 port to serial port in Ports tab. Then click the Save and Reboot button in

the lower right corner. Step 2, in the Configuration tab, for Receiver Mode, choose Serial_based receiver (SPEKSAT,

SBUS, SUMD); Serial Receiver Provider, choose SBUS. And click the Save and Reboot button in the lower right corner.

Here is the connection diagram with Crossfire Nano receiver. Using the UART1 on the FC board on the diagram below. Also, you could use the UART3 if you want. On Betaflight GUI, configure the UART1 port to recognise the Crossfire protocol. First, configure the UART1 port to serial port in Ports tab. Then click the Save and Reboot button in the lower right corner.
