Please note, ELRS is a new open source project so please only order this if you are comfortable with regular firmware updates as the firmware is still in beta. We will only be able to offer limited support due to the early nature of the firmware, but we think this project has great potential.
“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 the official ExpressLRS wiki
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
Receivers have ExpressLRS fw V1.1.0 preloaded without BINDING_PHRASE
1. Power on and off your receiver three times
2. Make sure the LED is doing a quick double blink, which indicates the receiver is in bind mode
3. Use the [BIND] button on the Transmitter Lua script, which sends out a binding pulse
4. Receiver will switch to slow blink once it has received binding pulse.
5. Power off and power on receiver again. If the receiver LED switch to solid on from slow blink, it’s bound with your transmitter.
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.
1. Connect receiver to USB-TTL module(RX-TX, TX-RX, 5V-5V, G-GND)
