RadioMaster RP3 V2 ExpressLRS 2.4GHz Nano Receiver (FCC) from Radiomaster — a compact and high-performance module for drones and quadcopters, combining minimal weight and dimensions with reliable 2.4GHz radio communication. The device is ideal for amateur and professional pilots who need stable telemetry, low latency, and the ability to update firmware via Wi-Fi.

Description and Key Features

The RP3 V2 is equipped with a temperature-compensated crystal oscillator (TCXO), ensuring reception stability under varying environmental conditions. At the heart of the module is the ESP8285 MCU, while the RF section is mentioned as SX1280IMLTRT in the description and SX1281 in the specifications, which should be considered when comparing revisions in detail. The receiver supports LoRa and FLRC modulation modes in the 2.4GHz band, allowing for long-range communication and stable telemetry with excellent penetration capability.

The model has a built-in Wi-Fi module for over-the-air (OTA) firmware updates without the need to physically remove the receiver from the aircraft. Binding is done using a binding phrase, which simplifies the setup process and eliminates the need for additional buttons or special connectors. To improve reception quality, the Skyworks SE2431L chip is used, which functions as a low-noise amplifier (LNA) and power amplifier (PA). The receiver supports telemetry with power up to 100 mW and has an antenna switching function, which increases connection stability during flights in complex conditions.
