Description:
The RadioMaster RP3 V2 ExpressLRS (ELRS) 2.4GHz Nano Receiver is a high-performance receiver engineered for FPV pilots who demand exceptional range, ultra-low latency, and reliable signal stability. Powered by the ExpressLRS open-source firmware, the RP3 V2 combines advanced RF technology with a compact, lightweight design, making it an excellent choice for FPV racing drones, freestyle quads, fixed-wing aircraft, helicopters, and other RC models.
Equipped with a Temperature-Compensated Crystal Oscillator (TCXO), the RP3 V2 delivers stable and accurate signal reception even under changing environmental conditions. Built around the ESP8285 MCU and Semtech SX1280 RF chipset, it supports both LoRa and FLRC communication modes, providing outstanding long-range performance while maintaining extremely low latency for precise control.
The RP3 V2 also features the Skyworks SE2431L RF Front-End Module, which includes a Low Noise Amplifier (LNA) for improved receiver sensitivity, a Power Amplifier (PA) capable of delivering up to 100mW telemetry output, and antenna diversity switching to ensure a stronger and more reliable radio link.
Built-in Wi-Fi connectivity enables fast and convenient firmware updates without removing the receiver from your aircraft. ExpressLRS Bind Phrase support eliminates the need for bind plugs or manual bind buttons, making setup quick and hassle-free.
Whether you're flying long-range missions, racing competitively, or performing freestyle maneuvers, the RadioMaster RP3 V2 offers dependable performance, excellent signal quality, and advanced telemetry in an ultra-compact package.
