GEPRC ELRS 915M/2.4G Gemini Xrossband receiver GEPRC ELRS 915M/2.4G Gemini Xrossband is a new dual receiver developed based on the open-source ExpressLRS project. It is built on Semtech's third-generation LR1121 RF chip and supports 150-960 MHz (sub-GHz) and 2.4 GHz bands for simultaneous dual-band transmission. The receiver uses two LR1121 chips, allowing easy switching between 915M Gemini, 2.4G Gemini and 915M+2.4G modes (requires dual-band transmitter support) when using 915M/2.4G antennas. It is fully compatible with existing ELRS 915M and 2.4G modules. In dual mode, it offers increased resistance to interference and higher stability. A temperature-compensated crystal oscillator (TCXO) ensures reliable performance even with temperature changes, with telemetry reaching up to 100mW. The built-in WiFi antenna allows for easy firmware updates and the SH1.0 connector makes installation easy. Features: - ExpressLRS 915M/2.4G dual frequency advanced system; - Built on Semtech's third generation LR1121 RF chip; - Compact dimensions of 18 × 23.6 × 5.7 mm and weight of only 1.7 g; - Supports 915M Gemini, 2.4G Gemini, 915M+2.4G Dual-Band modes; - TCXO – temperature compensated crystal oscillator for stable performance; - Telemetry power up to 100 mW; - Refresh rate up to 1000 Hz; - WiFi firmware update support; - SH1.0 connector for easy installation.
