Overview
The HGLRC ELRS GEMINI RX is a dual receiver available in 2.4G and 915MHz versions. It uses a dual-link design with dual-antenna reception and an RGB status LED, and supports WiFi firmware upgrades.
Key Features
- Dual communication link: antennas work at different frequencies at the same time for strong anti-interference performance.
- True diversity dual reception with dual-channel RF solution and dual-channel PA/LNA for stable signal reception.
- TCXO (temperature-compensated crystal oscillator) for more accurate frequency performance across temperature changes.
- Direct plug-in connection (plug and play) for faster replacement, while retaining pad design.
- Return power: up to 100mw (2.4G) / up to 50mw (915MHz).
- Refresh rate: up to 1000hz (2.4G) / up to 200hz (915MHz).
- WiFi firmware upgrade support.

Binding
The factory firmware version of HGLRC ELRS GEMINI RX dual receiver is 3.X or above. 3.X and 2.X firmware are not compatible, so the TX Module firmware needs to be upgraded to 3.X and above before binding.
- Power the receiver on and off 3 times continuously (power off after the light is on).
- After the rainbow gradient, the RGB light turns into an orange double flash state, indicating binding state.
- Use the ELRS remote control or TX Module to link to the receiver. If the RGB light changes from double flashing to solid, binding is successful.
What’s Included
- 1* HGLRC ELRS GEMINI RX (2.4/915) dual reception
- 1* (2.4G/915M) long antenna
- 1* (2.4G/915M) short antenna
- 1* heat shrink tube
