RadioMaster RP3 V2 ELRS 2.4GHz Diversity Nano Receiver — Receiver with Temperature-Compensated Crystal Oscillator from the Radiomaster brand — a compact and reliable solution for FPV drones, combining high reception sensitivity, low weight, and modern telemetry capabilities. This module is designed for stable signal reception in challenging flight conditions and is suitable for miniature, racing, and versatile quadcopters where every gram matters.

Brief Overview

The RP3 V2 is equipped with a temperature-compensated crystal oscillator (TCXO), which minimizes frequency drift during sharp temperature changes, ensuring communication stability in various climatic conditions. At the heart of the receiver is an ESP8285 chip paired with an SX1281 RF module, supporting Lora and FLRC communication modes for increased sensitivity and greater reception range. The built-in power amplifier (PA) allows telemetry transmission with an output power of up to 100 mW, significantly improving feedback over long distances.

Features and Benefits

• TCXO — temperature-compensated crystal oscillator for high frequency stability and minimized drift during temperature changes.

• Antenna Diversity — automatic switching between two antennas to reduce the risk of communication loss during aggressive maneuvers.

• Telemetry Power up to 100 mW thanks to the built-in amplifier (PA), ensuring reliable telemetry over long distances.

• Protocol Support Lora and FLRC for efficient operation with low power consumption and high sensitivity.

• ExpressLRS 2.4 GHz Compatibility — compatible with transmitters using ExpressLRS 2.4 GHz, with easy firmware update capability.

• Wi-Fi Firmware Updates — built-in Wi-Fi allows firmware updates without dismounting the receiver from the quadcopter, saving time and effort.

• Compact Size and Low Weight — optimal choice for micro and racing FPV drones where weight savings and mounting space are crucial.
