Traditional Binding
Receivers have ExpressLRS fw V2.0 preloaded without BINDING_PHRASE
1.Power on and off your receiver three times(After brushing the firmware, the first power on will automatically enter binding mode)

If use it as normal Serial receiver, flash it with Target JHEMCU EP24S 2400 RX
Flashing with ESP_NodeMCU-PyFlasher
1.Connect receiver to USB-TTL module(RX-TX, TX-RX, 5V-5V, G-GND)
2.Connect USB to PC while pressing and holding the boot button in.
3.open ESP_NodeMCU-PyFlasher
4.select Serial port of USB-TTL module, load bin firmware , select ??Dual Output(DOUT)nbsp; and ??Yes.wipes all data/div>5.click ??Flash NodeMCU/div>6.after flashing, Power off and power on your receiver, receiver will enter binding mode(quick double blink).
