Description
Experience next-level FPV performance with the RadioMaster RP1 2.4GHz ELRS Nano Receiver V2. Built around open-source ExpressLRS technology, the RP1 features an ESP8285 MCU and SX1280 RF chip for ultra-low latency and reliable long-range control. A built-in TCXO (temperature-compensated crystal oscillator) ensures stable signal reception in challenging environments, while integrated Wi-Fi enables easy firmware updates and configuration via a convenient WebUI.

Designed for both FPV racing and long-range flight, the RP1 is compatible with all 2.4GHz ExpressLRS modules and built-in 2.4GHz ELRS transmitters. Its compact Nano size and ultra-light design make it a perfect fit for drones, RC aircraft, and tight builds. The improved PCB design offers better heat dissipation, while the upgraded rigid T antenna provides durability and superior reception. With a simple CRSF bus interface, LED indicator on top, and user-friendly solder pads, the RP1 is the go-to receiver for RC hobbyists seeking uncompromised performance.
