GEPRC ELRS GemX Gemini Dual-Band Receiver — 915MHz + 2.4GHz, Semtech LR1121, TCXO, 25–1000Hz, 100mW Telemetry, 1.7g
The GEPRC ELRS GemX Gemini Receiver is a next-generation dual-band ExpressLRS receiver built on Semtech's third-generation LR1121 RF chip. Featuring dual LR1121 chips, it supports simultaneous 915MHz and 2.4GHz operation — giving pilots the flexibility to run either band independently or in true dual-band Xrossband mode for maximum link stability and interference rejection. At just 1.7g and 18×23.6mm, it's one of the most capable and compact ELRS receivers available.
Compatible with all existing 915M and 2.4G ELRS TX modules, the GemX Gemini is a direct upgrade for any FPV build where link reliability in congested RF environments matters.
Key Features
- True Dual-Band ELRS — Simultaneous 915MHz + 2.4GHz via dual LR1121 chips; switchable between 915M Gemini, 2.4G Gemini, and 915M+2.4G dual-RF modes
- Semtech LR1121 (3rd Gen) — Latest-generation RF chip covering 150–960MHz (sub-GHz) and 2.4GHz bands
- TCXO Temperature-Compensated Crystal Oscillator — Stable, drift-free frequency performance across temperature variations
- 25–1000Hz Refresh Rate — Full ELRS packet rate range for racing precision or efficient long-range cruising
- 100mW Telemetry Power — Strong return link for reliable RSSI, LQ, and sensor data at range
- Ultra-Compact & Lightweight — 18 × 23.6 × 5.7mm, 1.7g; minimal footprint for micro and 5" builds
- WiFi Firmware Updates — Built-in ESP32-PICO-D4 enables OTA firmware updates via WiFi
- SH1.0 Connector — Compact, secure connector for easy installation on modern FC boards
- IPEX1 (U.FL) Antenna Connector — Standard IPEX1 port for external antenna routing
