GEPRC ELRS 915M/2.4G C3 Gemini Xcrossband Receiver

The GEPRC ELRS 915M/2.4G C3 GemX Gemini receiver is a dual-band ExpressLRS system with Semtech LR1121 and ESP32-C3 chips, supporting 150-960 MHz and 2.4 GHz bands and simultaneous dual-band communication. The receiver supports up to 1000 Hz refresh rate, 915M Gemini, 2.4G Gemini and dual mode (with GemX TX), ensuring better immunity to interference and stable communication. The integrated TCXO, up to 100 mW telemetry power, WiFi updates and SH1.0 connection allow for convenient use, and after writing the TX firmware it can also function as a Gemini Xrossband TX module.
