Introducing the HappyModel EP1 Radio Receiver from the exclusive ELRS Nano Series. Its main hardware architecture is made with the ESP8285 MCU and SX1280 RF chip. It comes equipped with two, lightweight omni-directional antennas.
Due to the RF Module's low-latency and high-refresh-rate, this radio system is a great fit for both FPV Racing and Long Range FPV. It is also a perfect fit for any Tiny whoop because of the ultra-light, nano size.

- Maximum receive refresh rate: 500Hz
- Minimum receiver refresh rate: 25Hz
- Working voltage: 5v
- Weight: 0.01oz (0.42g) (without antenna)

- Supply power to the PP/EP1/EP2 RX, wait until the LED on the RX is off, then immediately turn off the power. Repeat the above steps once again. After the RX is powered on for the third time, the LED light will start to double-flash, which means that the RX has entered bind mode.
- First, copy the ELRS.LUA file to the SD-Card. Then, insert the ES24TX module or other 2.4G ELRS TX Module into the Radio Transmitter, and choose External RF mode to CRSF protocol. Find the ELRS menu, and select "ELRS", then select the [Bind] option. If the binding was performed successfully, the LED on the RX module will turn solid.
- Receiver LED Meaning:
- Solid: Bind Successful or Connection Established
- Double-flash: Bind Mode
- Slowly Flashing: No signal connection from the TX module
- Quickly Flashing: WiFi Hotspot Mode*
