GEPRC ELRS 915M/2.4G C3 Gemini Xrossband Receiver TX Module Dual-RF Chip 1000Hz FPV Quadcopter Longrange Freestyle Drone Parts

Summary

GEPRC ELRS 915M/2.4G C3 GemX Gemini Receiver is a new dual-band receiver system developed based on the ExpressLRS open-source project. It is designed with the Semtech LR1121 (3rd generation RF chip) and ESP32-C3 chip, supporting both 150960 MHz (sub-GHz) and 2.4 GHz bands, delivering advanced simultaneous dual-band transmission.
It supports up to 1000 Hz (FSK) refresh rate and comes with 915M/2.4G dual-band antennas, allowing flexible switching between 915M Gemini, 2.4G Gemini, and 915M+2.4G Dual-Band modes (It requires the use of GemX TX). When operating in dual-band mode, the system achieves enhanced anti-interference performance and more stable connectivity, ensuring excellent results for both close-range racing and long-range flights. It is also fully compatible with single-band ELRS TX modules, offering outstanding versatility.

Equipped with a TCXO, it maintains frequency stability under varying temperatures. The TLM power reaches up to 100 mW, and the receiver features a built-in WiFi antenna for easy firmware upgrades via WiFi. With the SH1.0 connector, installation is simple and efficient. Additionally, after flashing TX firmware, it can function as a Gemini Xrossband TX module.
