HappyModel ELRS TCXO Nano Receiver Series (EP1, EP2, Dual RX)

This is the HappyModel ELRS TCXO Nano receiver series.

The EP1 TCXO uses a temperature compensated crystal oscillator which means accurate MCU clock frequency for improved performance and reliability of your RC link.

The EP1, EP2, and EP1 Dual receiver’s  are based on the ESP8285 MCU that allows for upgrading via WiFi, along with the SX1280(SX1281)IMLTRT RF Module.

Despite the tiny size of these ELRS receivers, you can still expect low latency and high refresh rate of your ELRS system.

The HappyModel TCXO series of receiver’s can be used on any size FPV quadcopter.

The Happymodel EP1 RX includes a IPEX connector for a dipole antenna, while the EP2 RX includes a built in SMD antenna.

Please note, ELRS is a new open source project so please only order this if you are comfortable with regular firmware updates as the firmware is still in beta.  We will only be able to offer limited support due to the early nature of the firmware, but we think this project has great potential.
