Wiring Diagram & Binding Procedure

Binding procedure

Supply power to the flight controller by plug USB, wait until the green LED on the FC is off, immediately turn off the power, and then repeat again the above steps. When the FC is powered on for the third time, the green LED light will start to double-flash, which means that the RX enters the binding mode
Please make sure your ExpressLRS tx module firmware is v3.x.x. And go to ExpressLRS.lua from “TOOLS” menu of your radio transmitter. Then hit [Bind] to binding with the onboard ExpressLRS receiver. The green LED should blinking slowly first then turn to solid, that means binding was successfully. If the green led still keep double flash after binding ,please change Model Match tab value from “off” to “on” or from “on” to “off”

Receiver LED status meanings

Green LED solid means bind successful or RC link established; Green LED double-flash means get into bind mode; Green LED flash slowly means no RC signal input from TX module; Green LED continuous flash fast means ExpressLRS wifi enabled.

Bind successful
