Firmwares

• ExpressLRS 3.0 or newer,   DIY 2.4 GHz / DIY 2400 RX PWMP EX
• ExpressLRS wiki for PWM receiver, Click HERE
• Make sure Receiver and TX module both are running ExpressLRS 3.0 or newer

——————————————————-

• Receiver has ExpressLRS 3.0 preloaded with binding phrase “123456”,  the Receiver will never enter binding mode if using the traditional binding procedure.
• You need to reflash it with your binding phrase OR go into WebUI to set your binding phrase.

Flashing via Wifi

• Disconnect ESC and servos from receiver first.
• Power on receiver by 5V source. Receiver’s LED(Red) will blink slow at first, and after 20s, it should blink fast indicating it’s on Wifi Hotspot Mode.
• More detailed steps,  pls refer this page.
• Target: DIY 2.4 GHz / DIY 2400 RX PWMP EX

Flashing via UART

1. Disconnect ESC and servos from receiver first.
2. Wire the receiver into the USB-TTL adapter, with TX on receiver connected to the Rx on the USB-TTL, and RX on receiver connected to the Tx of the USB-TTL. Wire 5V and GND of the USB-TTL to 5V and GND of the Receiver.
3. Press the boot button while powering on the receiver, then release – the Red LED on receiver should now be solid.
4. Select the target DIY 2.4 GHz / DIY 2400 RX PWMP EX  and  “UART” for Flashing Method,  set your bind phrase and Firmware Options and once done, click on Build and Flash.
