Happymodel ELRS Nano 2.4GHz EP1 RX

The Happymodel 2.4GHz ELRS nano series receiver has an open-source program based on ExpressLRS. Due to the low-latency and high-refresh-rate RF module, they are very comfortable for FPV Racing and Long Range FPV. These are very suitable for Tiny whoops because of the ultra-light and Nano size!

Binding procedure:

1. Supply power to the PP/EP1/EP2 RX, wait until the LED on the RX is off, immediately turn off the power, and then repeat again the above steps. When the RX is powered on for the third time, the LED light will start to double-flash, which means that the RX enters the binding mode.

2. Insert the ES24TX module or other DIY 2.4G ELRS TX to Radio transmitter, and choose External RF mode to CRSF protocol, then you can find the ELRS menu from the Radio systems(Need to copy the ELRS.LUA file to the SD-Card tools first), Enter into ELRS and press [Bind], the LED on the RX module will be getting solid if bind is successful.

3. Receiver LED status meanings:

PP RX: LED solid means bind successful or Connection established; LED double-flash means in bind mode; LED flash slowly means no signal connection from the TX module

EP1/EP2 RX: LED solid means bind successful or Connection established; LED double-flash means in bind mode; LED flash slowly means no signal connection from the TX module; LED flash fast means in WIFI hotspot mode, you can connect the WIFI of the RX and upgrade the firmware of the RX via visit 10.0.0.1 from the web browser(password: expresslrs)
