Summary The GEPRC ELRS 915M/2.4G Gemini Xrossband Receiver is a new dual-band system developed from the ExpressLRS open-source project. It is designed based on Semtech’s third-generation LR1121 RF chip, supporting 150 – 960MHz (sub-GHz) and 2.4GHz bands for simultaneous dual-band transmission. The ELRS 915M/2.4G Gemini Xrossband Receiver features dual LR1121 chips, allowing easy switching between 915M Gemini, 2.4G Gemini, and dual-band 915M+2.4G modes (requires dual-band TX module support) when paired with 915M/2.4G antennas. It is fully compatible with existing 915M and 2.4G ELRS TX modules. In dual-frequency mode, it provides enhanced anti-interference and stability. The TCXO temperature-compensated crystal oscillator ensures reliable performance across temperature variations, with telemetry power up to 100mW. The built-in WiFi antenna facilitates effortless firmware updates, and the SH1.0 connector simplifies installation.
