Due to the low-latency and high-refresh-rate RF module, they are very comfortable for FPV Racing and Long Range FPV. These are very suitable for Tiny whoops because of the ultra-light and Nano size!\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eThe Series\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eThere are three in this series. The PP RX is designed by @Jye Smith from the ExpressLRS development team. Its 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.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eThe Update\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eOn the basis of PP RX, Happymodel has developed the Nano 2.4GHz RX version of the ESP8285 named EP1 and EP2. The RF module of EP1\/EP2 is the same as PP RX and uses ESP8285 MCU. You can upgrade firmware by WiFi!
