SuperX Nano Receiver:


SuperX Mono Receiver:

Gemini offers three modes: 900M Gemini, 2.4G Gemini, and 900M+2.4G Gemini Xrossband (GemX). With GemX, you no longer need to choose between performance traits—it combines 2.4GHz's low latency and 900MHz's long-range in a single, seamless link.

Note: The GemX mode requires a dual-band TX.

SuperX Nano: 900M+2.4G Dual Band

Powered by dual LR1121 chips from Semtech, the SuperX Nano Receiver delivers uncompromising signal reliability with three modes: 900M Gemini (long-range penetration), 2.4G Gemini (ultra-low latency), and 900M+2.4G GemX (simultaneous operation). The included dual-band T antennas eliminate frequency-switching hassles, while advanced diversity processing ensures rock-solid stability in RF-challenged environments. Built for mission-critical applications, it's the ultimate solution for competitive racers, long-range explorers, and professional aerial photographers who demand zero-compromise performance.

SuperX Mono: Band-switching Agility

The compact and lightweight SuperX Mono Receiver harnesses a single LR1121 chip with a dual-band antenna, enabling seamless switching between 900M and 2.4G. This cost-effective solution maintains impressive 1000Hz packet rates (in FSK mode) while offering exceptional value, making it ideal for micro builds and budget-conscious pilots who need versatile performance in both close-range freestyle and long-distance applications.

TX Compatibility

Configuration

The SuperX Receiver currently supports CRSF/SBUS/SUMD protocols. The following takes CRSF protocol as an example to introduce its connection and pin configuration with Betaflight firmware flight controller.

Wiring diagram:

Note: Betaflight and ExpressLRS use different JST SH connector pin configurations. Betaflight: 5V (V+), GND, RX, TX; ExpressLRS: GND, 5V (V+), TX, RX. When using the terminal wires for connection, please check the sequence.

Connect the flight controller to the Betaflight Configurator for basic configuration. First, on the "Port" tab, enable the flight controller serial port like UART1 as Serial Rx.

On the "Configuration" tab, set Receiver Mode to Serial (via UART) and Serial Receiver Provider to CRSF.

Bind

The SuperX Receiver uses ExpressLRS V3.x official protocol as its default firmware without a pre-set binding phrase. For successful operation, ensure the transmitter module also uses ExpressLRS V3.x or later firmware with no pre-set binding phrase.

1. Power-cycle the receiver 3 times with a 1-second interval or press and hold the BOOT button for 2 seconds to enter binding mode.

2. The RGB indicator flashes orange twice, which indicates the receiver is in bind mode.

3. Configure remote control or transmitter module to bind with the receiver. If the RGB indicator is a solid light, it's bound!
