Description

The RadioMaster RP3 ExpressLRS Receiver is a compact 2.4GHz nano receiver designed for reliable control and low-latency communication in compatible FPV drones. Its compact design makes it suitable for builds where space and dependable radio performance matter.

Experience exceptional control, long-range performance, and ultra-low latency with the RadioMaster RP3 ExpressLRS (ELRS) 2.4GHz Receiver, available at Multirotors. Designed for FPV pilots, racers, freestyle enthusiasts, and long-range drone builders, the RP3 combines advanced RF technology with a compact design to deliver a reliable and responsive radio link.

The RP3 is powered by the ESP8285 microcontroller and the Semtech SX1280 RF chip, utilizing the latest ExpressLRS (ELRS) 2.4GHz open-source firmware. This combination provides outstanding range, low latency, and dependable communication, making it ideal for demanding FPV applications.

To ensure stable performance in changing weather conditions and varying temperatures, the RP3 features a built-in Temperature-Compensated Crystal Oscillator (TCXO). The TCXO maintains highly accurate frequency stability, resulting in consistent signal quality and improved reliability throughout every flight.

For enhanced reception and telemetry performance, the RP3 integrates the Skyworks SE2431L RF front-end module, featuring 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 maintain a stronger and more reliable connection in challenging environments.

Built-in Wi-Fi support allows quick firmware updates directly through your computer or mobile device without removing the receiver from the aircraft. The receiver also supports Bind Phrase, making setup faster and more convenient by eliminating the need for bind plugs or manual bind button procedures.

Whether you're building a racing quad, freestyle drone, cinematic FPV platform, or long-range UAV, the RadioMaster RP3 provides the performance and reliability trusted by FPV pilots worldwide.
