Based on ELRS V3.3 and collaborated with ELRS developer team, the First Ever Gemini Dual-Frequency Diversity Transmitter comes out! At present, SuperG Nano Transmitter can be fully activated to achieve the best link quality ever combined with diversity rx such as SuperD receiver or SuperP receiver. With dual 1W transmit power, it excels in anti-interference performance and stability, making it the ideal solution for demanding applications like FPV racing, long-range flight, and professional photography.
Bullet Point
Introducing the pioneering Gemini Dual-Frequency Diversity Transmitter, propelling ELRS into the era of dual-frequency capabilities.
Dual 1W transmit power experienced amplified signal strength, expanded transmission distances, and a substantial increase in remote control range.
In conjunction with existing true diversity receivers, activating the Gemini mode ensures unwavering signal stability even in the most intricate radio environments.
Meticulously crafted from CNC aluminium alloy, the transmitter casing facilitates efficient thermal conductivity, complemented by an intelligently designed Heatsink system for optimal heat dissipation.
Featuring 2 customizable buttons and 1 USB port, the transmitter accommodates external power sources, enabling steadfast long-range expeditions.
Below is the diagram for the SuperG Nano Transmitter.
Note: Please assemble the antenna before powering on. Otherwise, the PA chip in the SuperG Nano Transmitter will be damaged permanently.

Know More About Diversity & Gemini
Antenna Diversity mode, two antennas. Switch the two antennas regularly to read the RSSI value of the signal and determine which antenna to use to receive data.
True Diversity mode, where both antennas receive data at the same frequency, and the antenna that receives the correct data first is used.
Gemini mode, where two antennas simultaneously receive telemetry data with a frequency difference of 40MHz. They also transmit data simultaneously but at different frequencies. This means that you can receive the same data packets on different frequencies and antennas. This mode provides stable flight even in complex radio environments.
Among them, Gemini is the most advanced function yet of ExpressLRS - Gemini mode currently! It owns the most stable mode for receiving signals and offers higher resistance to interference and stability, making it suitable for various applications.
SuperG Nano Transmitter features Gemini mode. In atesting video by developer Jye Smith, it is shown that with a refresh rate of 1000Hz, the LQ value fluctuates between 90-100 when the true diversity receiver is in operation. However, after switching to Gemini mode, the LQ value stabilizes at 99-100. This demonstrates that ELRS goes to great lengths to ensure link stability.
Combination with Diversity RX
Gemini mode is built upon the hardware foundation of true diversity receivers and requires a dual RF output high-frequency module. When used with Super series products, the advantages of Gemini mode can be fully utilized. And The effects of using the transmitter and receiver in various modes are as follows:

Using it together with True Diversity Receiver ensures a super stable yet strong radio link for pilots to fly in any environment that require extremely stable signals and low latency. Including long-range flights, multiplayer flights, and FPV racing. It gives pilots a robust and aggressive flight experience.
Dual 1W Output Power
The SuperG Nano Transmitter with Dual-active Antennas@Dual Frequencies, each boasting a powerful 1W transmission power. Experience stronger signals, longer transmission distances, and enhanced remote control range.
Cooling System Iteration
The casing part is made of CNC aluminium alloy with an anodized surface for durability. It efficiently dissipates heat, thanks to its optimized internal airflow and high-speed fan with copper heat fins. Fly with confidence and enjoy reliable performance every time.
Combination with Most Radio TX
The SuperG Nano Transmitter could be configured via LUA script. EdgeTX and OpenTX radio transmitter that supports CRSF could be used easily. It available for popular Nano interface TX when used with Micro-Nano Module Adapter including Radiomaster TX16, Boxer, Zorro. Jumper T16, T20, T Pro. Frsky QX7, X9, X Lite.
Note: LiteRadio 3 Pro Radio Transmitter cannot support dual transmitter power above 100mW due to power supply issues.
ELRS Series
The ExpressLRS Series expands its lineup with the addition of SuperG Nano Transmitter. To achieve exceptional link quality, pair the Gemini TX with Super series diversity receivers. BETAFPV takes the flying experience to new heights by introducing ELRS links that offer long-range capabilities, low latency, and high refresh rates in a radio control system.
The SuperG Nano Transmitter's default firmware is ELRS V3.3.0, and users need to update the receiver to V3.0.0 or above to bind the frequency.
