RX SoloGood Gemini Dual Band Diversity 915M/2.4G

SoloGood Gemini Dual Band Diversity 915M/2.4G is an ExpressLRS receiver with two Semtech LR1121 radios and two antenna ports. It can run 915 MHz and 2.4 GHz at the same time (Xrossband) or send the same link on two frequencies within one band (Gemini).

Features

• Two independent RF paths — two LR1121 chips, each with its own antenna (true diversity).
• 915 Gemini, 2.4 Gemini and 915+2.4 Xrossband modes, selected by the transmitter.
• Two dual-band T antennas included.
• 100 mW (20 dBm) telemetry.
• ESP32-C3 with Wi-Fi for firmware updates and configuration.

Specifications

• Protocol: ExpressLRS (CRSF output)
• MCU: ESP32-C3
• RF chips: 2× Semtech LR1121
• Bands: 915 MHz and 2.4 GHz
• Telemetry power: 100 mW (20 dBm)
• Antenna connectors: 2× IPEX1
• Input voltage: 3.6–5.5 V
• Pads: GND, 5V, TX, RX

Package

• SoloGood Gemini Dual Band receiver — 1 pc
• Dual-band 915 MHz / 2.4 GHz T antenna, IPEX1 — 2 pcs
• Connection cable — 1 pc
• Heat shrink — 2 pcs

Compatibility

• Transmitters: ExpressLRS 3.x. Simultaneous 915 MHz + 2.4 GHz (Xrossband) requires a dual-LR1121 Gemini (GemX) transmitter; with single-band 2.4 GHz or 900 MHz transmitters it works in that band.
• Firmware: ELRS major version, regulatory domain and binding phrase must match the transmitter.
• Flight controllers: Betaflight, INAV, ArduPilot via a free UART, CRSF protocol, 5 V.
