"Any ELRS 2.4Ghz receivers can work with any ELRS 2.4Ghz TX Modules, from any manufacturer and even the DIY ones. 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
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.
Firmwares:
ELRS_V1.1.0_NoPhrase_ELRS-R24-D.bin
ELRS_V1.1.0_NoPhrase_ELRS-R24-S.bin
Tool: ESP_NodeMCU-PyFlasher.exe
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).
Flashing with ELRS configurator:
MATEK_2400_RX target is not available in ELRS configurator 1.0.8 and fw release 1.1.0 for now
