GEPRC ELRS 915M/2.4G C3 Gemini Xrossband – Next-Generation Dual-Band ExpressLRS Receiver

GEPRC ELRS 915M/2.4G C3 Gemini Xrossband is a high-performance ExpressLRS receiver that combines dual-band technology, exceptional reliability, and ultra-fast communication. Designed for demanding FPV pilots, it delivers maximum link stability for both racing and long-range flights. By operating simultaneously on 915 MHz and 2.4 GHz frequency bands, Gemini Xrossband offers significantly greater resistance to interference than conventional single-band receivers.

Advanced Gemini Xrossband Technology

GEPRC ELRS 915M/2.4G C3 Gemini Xrossband is built on the open-source ExpressLRS platform and features two third-generation Semtech LR1121 RF transceivers paired with a modern ESP32-C3 processor. This hardware combination supports 915 MHz Gemini mode, 2.4 GHz Gemini mode, and simultaneous 915 MHz + 2.4 GHz dual-band operation. Dual-band mode delivers a more reliable control link in environments where radio interference can negatively affect traditional receivers.

Using both frequency bands simultaneously significantly reduces the risk of signal loss while improving control link reliability in demanding environments such as urban areas, forests, mountainous terrain, and long-range FPV missions. The result is a safer flying experience and greater control over your aircraft, even under challenging conditions.

Outstanding Performance with Ultra-Low Latency

GEPRC ELRS 915M/2.4G C3 Gemini Xrossband supports update rates ranging from 25 Hz to 1000 Hz using both LoRa and FSK protocols. High refresh rates ensure extremely low latency and rapid response to control inputs, making the receiver an excellent choice for racing drones and aggressive freestyle flying.

A built-in temperature-compensated crystal oscillator (TCXO) maintains frequency stability even under significant temperature fluctuations. This ensures dependable performance in both freezing winter conditions and hot summer environments. Telemetry output power reaches up to 100 mW, providing a strong and stable telemetry link between the flight controller and transmitter.

Easy Installation and Wireless Firmware Updates

With compact dimensions of just 18 × 23.6 × 5.7 mm and a weight of only 1.6 g, the receiver is perfectly suited for compact FPV builds where every gram matters. A standard SH1.0 connector simplifies installation and allows for quick integration with compatible flight controllers.

The receiver also includes a built-in Wi-Fi antenna, enabling wireless firmware updates without removing the receiver from the aircraft. This makes maintenance and software updates fast, convenient, and user-friendly.

Broad Compatibility

GEPRC ELRS 915M/2.4G C3 Gemini Xrossband is compatible with both Gemini Xrossband transmitter modules and standard ExpressLRS 915 MHz and 2.4 GHz transmitters. It supports widely used output protocols including CRSF, SBUS, SUMD, MAVLink, and DJI RS2 Pro, making it suitable for FPV drones, fixed-wing aircraft, rovers, and professional remote-control applications.
