  • $16.99

This is a crazy small RX designed by Jye Smith from ExpressLRS. The main hardware architecture is STM32L432KBU6 MCU and SX1280 RF chip. It has a built-in ceramic antenna, which is super light and small in size. 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 as PP RX and uses 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 races and Long Range FPV. And very suitable for whoop because of the ultra-light and Nano size.
