Experience the absolute bleeding edge of RC link technology with the GEPRC ELRS 915M/2.4G C3 Gemini Xrossband Receiver. Built around the revolutionary third-generation Semtech LR1121 RF chip and the powerful ESP32-C3, this receiver shatters the limitations of traditional radio links. By supporting simultaneous dual-band transmission across both 915MHz and 2.4GHz frequencies, it delivers an unbreakable connection that thrives in both close-range band racing and extreme long-range mountain surfing.

True Gemini Xrossband Technology

Why choose between the low latency of 2.4GHz and the deep penetration of 915MHz when you can have both? When paired with a compatible GemX TX module, this receiver allows for flexible switching between 915M Gemini, 2.4G Gemini, and simultaneous 915M+2.4G Dual-Band modes. This dual-RF approach offers unparalleled anti-interference performance. Even if one frequency band gets overwhelmed by local noise, the other keeps you locked in and flying safely. (Note: Fully backward compatible with standard single-band ELRS TX modules!)

Unwavering Stability & Telemetry

Temperature swings can cause crystal oscillators to drift, leading to sudden failures. GEPRC solved this by integrating a high-precision TCXO (Temperature-Compensated Crystal Oscillator), ensuring your frequency remains absolutely stable whether you are flying in freezing snow or sweltering summer heat. Furthermore, it boasts a massive 100mW telemetry output, guaranteeing your radio receives critical drone data (like battery voltage and GPS coordinates) even at extreme distances.

Builder-Friendly & Insanely Versatile

Despite housing two RF chips and a TCXO, this powerhouse weighs only 1.6g. Installation is a breeze thanks to the included plug-and-play SH1.0 connector—no micro-soldering required unless you want to! Firmware updates are completely wireless via the built-in WiFi, and for the ultimate tinkerers, this receiver can even be flashed with TX firmware to function as a standalone Gemini Xrossband TX module!
