  • $17.99

The Happymodel EP1 TCXO RX is a nano-sized true diversity 2.4GHz ELRS receiver with RF amps. This TCXO Rx receiver uses a temperature-compensated crystal oscillator to help with accurate MCU clock frequency, thus improving the performance and reliability of your RC link. Despite the small size, the low latency and high refresh rate of the ELRS system allow this receiver to be used on full-size/long-range quads, while also being small enough to be used on whoop-size quads! The Happymodel EP1 RX includes an IPEX connector for a dipole antenna, while the EP2 RX includes a built-in SMD antenna.

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