Product Details
2.4GHz 868/900MHz 915MHz ELRS Dual Band Gemini Receiver Semtech LR1121 ELRS Transceiver
Description:
The 900/2400 Dual Band Gemini RX dual-band receiver is a wireless control system optimized and developed based on the ExpressLRS open-source project. It uses the Semtech third-generation LR1121 transceiver and can be configured for sub-GHz frequencies ranging from 150-960MHz or 2.4GHz LoRa. The sub-GHz range is fully compatible with the current ELRS433/868/900 range and features +100mW output capability, with the SX1276 supporting a maximum output power of +50mW. It is also fully compatible with all 2.4GHz LoRa modes.
However, it doesn’t support FLRC mode or 2.4GHz D and F modes currently.
Dual-band four-channel transmission at the same time, and at the interval of 10-40MHz at the same time uninterrupted frequency hopping, anti-interference ability is stronger.
