GEPRC GemX Gemini Dual-Band ELRS Receiver
Build a flexible ExpressLRS control link with the GEPRC GemX Gemini receiver. Its listed dual LR1121 RF chips support 915MHz and 2.4GHz operation, with single-band Gemini and dual-band Xrossband modes available when paired with compatible transmitter hardware and firmware.
During your next FPV build, plan the antenna routes, verify the flight-controller wiring and select a supported packet rate before your first range check. The compact receiver provides configuration flexibility without making every transmitter a dual-band system.
Key Features
- Dual LR1121 RF chips: Listed support for 915MHz Gemini, 2.4GHz Gemini and 915MHz/2.4GHz Xrossband modes.
- TCXO: Temperature-compensated frequency reference.
- 25–1000Hz listed packet-rate range: Available rates depend on the selected band, transmitter and firmware mode.
- 100mW listed telemetry power: Actual operation depends on configuration and supported settings.
- Wi-Fi firmware updates: Listed ESP32-PICO-D4 controller supports wireless firmware updating.
- Compact installation: Listed dimensions of 18 × 23.6 × 5.7mm and receiver-only weight of 1.7g.

Transmitter and Flight-Controller Compatibility
Confirm ExpressLRS firmware compatibility, matching frequency configuration and supported packet rates before binding. A compatible single-band transmitter can use a supported matching-band mode; simultaneous dual-band Xrossband operation requires transmitter hardware and firmware that support it. Do not assume universal compatibility with every existing 915MHz or 2.4GHz module.
Installation requires an appropriate flight-controller serial connection, a suitable regulated 5V supply and correctly matched wiring. An available UART or matching connector alone does not establish plug-and-play compatibility. Verify the pinout before applying power.

Perfect For
FPV pilots and builders planning a configurable ELRS link for racing, freestyle or distance-oriented builds. Link performance depends on installation, antennas, interference and settings; no specific range or uninterrupted connection is guaranteed.
Installation Checklist
- Disconnect aircraft power before wiring or fitting the receiver.
- Verify supply voltage, ground and signal pin assignments.
- Fit compatible antennas and route them clear of propellers and moving parts.
- Confirm binding, channel operation, telemetry and failsafe behavior before flight.
- Perform the range checks specified by your radio-system instructions.
