BetaFPV SuperX Gemini Xross Mono Receiver

The BetaFPV SuperX Gemini Xross Mono is an ELRS receiver built around a single Semtech LR1121 chip, letting a build switch between the 900MHz and 2.4GHz bands from one compact receiver — 900MHz favours extended range, while 2.4GHz favours lower latency.

Key features

• Single LR1121 RF chip paired with an ESP32-C3 MCU for band-switching between 900M and 2.4G.
• Runs the CRSF, SBUS, SUMD, DJI RS2 Pro and MAVLink serial protocols, covering most flight controllers and goggle links.
• Weighs just 0.82g and measures 12.3 x 18.6mm, suited to 2 to 5-inch drones where every gram matters.
• Single U.FL antenna connector keeps wiring simple on space-constrained builds.
• Ships with a dual-band T antenna, a single-ended SH1.0 connector and heat-shrink tubing for a tidy install.
