This is as long as they have the same binding phrase and configuration options (Regulatory Domain, Performance Options and Extra Data).” More details about ExpressLRS, pls check out ExpressLRS wiki Wiring with FC Receiver RX — FC UART_TX for Telemetry Receiver TX — FC UART_RX for Control Receiver 5V — FC 5V or 4v5 Receiver G — FC GND Receiver protocol: Serial-based receiver – CRSF Product Guidance Traditional Binding Receivers have ExpressLRS fw 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. Flashing with ESP_NodeMCU-PyFlasher Connect receiver to USB-TTL module(RX-TX, TX-RX, 5V-5V, G-GND) Connect USB to PC while pressing and holding the boot button in. open ESP_NodeMCU-PyFlasher select Serial port of USB-TTL module, load firmware, select “Dual Output(DOUT)” and “Yes.wipes all data“ click “Flash NodeMCU“ after flashing, Power off and power on your receiver, receiver will enter binding mode(quick double blink).
