BetaFPV SuperX RX Nano – Dual-Band ExpressLRS Receiver for Maximum Link Reliability

The BetaFPV SuperX RX Nano is a next-generation ExpressLRS (ELRS) receiver that combines 2.4 GHz and 900 MHz radio frequencies into one compact device while supporting advanced Gemini and Diversity operating modes. Designed for pilots who demand the highest level of control link reliability, it is an ideal solution for freestyle, racing, cinematic, and long-range FPV flights.

Equipped with dual Semtech LR1121 RF chips and two antennas, the BetaFPV SuperX RX Nano can operate on both frequency bands simultaneously, significantly reducing packet loss and improving connection stability even in challenging RF environments. This makes it an excellent choice for professional pilots and anyone unwilling to compromise on flight safety or control performance.

Gemini Technology for Maximum Link Reliability

The standout feature of the BetaFPV SuperX RX Nano is its Gemini technology, which enables simultaneous operation on both 2.4 GHz and 900 MHz frequency bands. Unlike conventional ELRS receivers that rely on a single radio frequency, both frequency bands operate in parallel.

If one frequency experiences interference or reduced signal quality, the control link remains active through the other band. This dramatically reduces the risk of signal loss and provides greater confidence when flying in challenging environments such as urban areas, forests, or on extended long-range missions.

In addition to Gemini mode, the receiver also supports Diversity mode, utilizing two antennas to automatically optimize signal reception and further improve link reliability.

Modern Hardware for Professional FPV Applications

The BetaFPV SuperX RX Nano is built around modern hardware featuring an energy-efficient ESP32-C3 microcontroller and dual Semtech LR1121 RF chips. This advanced architecture supports the latest ExpressLRS features while delivering fast data processing and dependable radio communication.

The receiver supports up to 20 dBm telemetry output power, allowing the flight controller to transmit important information such as battery voltage, GPS data, and other telemetry information back to the pilot over extended distances.

Wide Protocol Support and Excellent Compatibility

The BetaFPV SuperX RX Nano is fully compatible with the ExpressLRS ecosystem and supports several popular communication protocols, including CRSF, SBUS, SUMD, DJI RS2 Pro, and MAVLink.

This makes it suitable for a wide range of applications, from traditional FPV racing drones to cinematic platforms, long-range aircraft, autonomous UAVs, and other remotely operated systems.

Thanks to its standard UART interface, installation is quick and straightforward, with compatibility across most modern flight controllers.

Compact Size with Professional Performance

Although the BetaFPV SuperX RX Nano offers dual-band operation and dual RF chips, it remains remarkably compact. Its lightweight design allows it to be installed even in smaller freestyle and racing drones without adding significant weight.

The dual U.FL antenna connectors allow antennas to be positioned for optimal reception, improving signal quality while minimizing interference caused by frame shielding.

Technical Specifications

The BetaFPV SuperX RX Nano features an ESP32-C3 microcontroller and dual Semtech LR1121 RF chips, supporting simultaneous operation on both the 900 MHz and 2.4 GHz frequency bands.
