by RadioMaster

Description:
Experience enhanced performance and reliability with the RadioMaster RP3 ELRS 2.4ghz Nano Receiver V2. Designed for demanding FPV drone pilots, this ultra-compact receiver comes equipped with a built-in TCXO (temperature-compensated crystal oscillator) to maintain stable and precise signal reception. Its optimized PCB improves heat dissipation, while the integrated Skyworks SE2431L module boosts range through a powerful LNA (low-noise amplifier) and PA (power amplifier), supporting up to 100mW telemetry output.

Developed around the ESP8285 MCU and the SX1281 RF chip, the RP3 supports ExpressLRS 2.4GHz firmware for a low-latency link and extended coverage. With Wi-Fi built in, firmware updates can be done directly on your aircraft—no more removing the receiver or juggling bind plugs. Antenna diversity ensures consistent signal quality, and the receiver can bind effortlessly via a bind phrase. Compatible with 2.4GHz ExpressLRS modules and transmitters, the RP3 is the ideal choice for pilots seeking long-range, stable performance, and easy setup.
