Radiomaster 2.4GHz ExpressLRS EP1 Nano Receiver

The Radiomaster ExpressLRS 2.4GHz EP1 Nano Receiver is based on the open-source ExpressLRS project. Designed by @Jye Smith from the ELRS development team, the rx uses the STM32L432KBU6 MCU and SX1280 RF chip.

Due to the low-latency and high-refresh-rate RF module, they are very comfortable for FPV races and Long Range FPV.  They are also very suitable for Tiny whoop because of the ultra-light Nano size.
