Happymodel EP1 2.4GHz RX ELRS Receiver

The PP RX is designed by @Jye Smith from ExpressLRS development team. Its main hardware architecture is STM32L432KBU6 MCU and SX1280 RF chip. On the basis of PP RX, we have developed the Nano 2.4GHz rx of ESP8285 version named EP1 and EP2.  The RF module of EP1/EP2 is the same like PP RX and use ESP8285 MCU . So you can upgrade firmware by WIFI , that’s too simple. Due to the low-latency and high-refresh-rate RF module, they are very comfortable for FPV race and Long Range FPV. And very suitable for whoop because of the ultra light and Nano size.
