HGLRC ELRS Gemini RX 2.4G Dual Receiver

The HGLRC ELRS Gemini 2.4GHz is a true diversity receiver built to maintain a flawless control link in heavy RF interference. Unlike traditional antenna-switching diversity, the Gemini protocol utilises two separate RF chips to process packets simultaneously across different frequencies. This eliminates blind spots and switching delays, making it an essential upgrade for long-range mountain surfing, professional cinelifters, or dense bando environments where a failsafe is not an option.

Key features

• True dual-channel reception via the ExpressLRS Gemini protocol
• Integrates dual RF chips to completely eliminate antenna switching delay and packet loss
• Built-in TCXO (Temperature Compensated Crystal Oscillator) ensures reliable frequency lock-on during extreme heat or winter flights
• Standard IPEX1 (U.FL) connectors allow easy swapping of antennas to suit your specific frame layout
• Flashes quickly and easily via native Wi-Fi or Betaflight UART passthrough

Specifications

• MCU: ESP32
• RF Chip: Dual SX1280 / SX1281
• Frequency band: 2.4GHz ISM
• Input voltage: 5V
• Antenna connector: 2x IPEX1 (U.FL)
• Supported firmware: ExpressLRS (requires ELRS V3.3 or newer for Gemini features)

Note: To leverage the full simultaneous-transmission benefits of this receiver, pair it with a Gemini-capable ExpressLRS transmitter module. It remains fully backward compatible with standard single-antenna ELRS transmitters, operating as a standard true-diversity receiver.
