Wiring with FC
- Receiver RX — FC UART_TX for Telemetry
- Receiver TX — FC UART_RX for Control

- Receiver G — FC GND
- Receiver protocol: Serial-based receiver – CRSF
Traditional Binding
- Receivers have ExpressLRS fw V1.1.0 preloaded without BINDING_PHRASE
- Power on and off your receiver three times
- Make sure the LED is doing a quick double blink, which indicates the receiver is in bind mode
- Use the [BIND] button on the Transmitter Lua script, which sends out a binding pulse
- Receiver will switch to slow blink once it has received binding pulse.
- Power off and power on receiver again. If the receiver LED switch to solid on from slow blink, it’s bound with your transmitter.
- Important: If the RX firmware has a bind phrase, the RX will never enter binding mode using the above procedure. It must be flashed without a binding phrase to do traditional binding.
