FPV made simple!
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.
Note: Please assemble the antenna before powering on. Otherwise, the PA chip in the SuperG Nano Transmitter will be damaged permanently.

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 a testing 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.
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.
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.
The casing part is made of CNC aluminum 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.
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.
SuperG Nano Transmitter is a cutting-edge device that offers a distinct and personalized flair, with a range of three vibrant color options including red, grey, and black. The combination of its sleek design, superior functionality, and colorful choices perfectly caters to those who seek elevate style and performance.
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.
SuperG Nano Transmitter is designed to receive signals using the Crossfire Serial Data Protocol (CRSF). Therefore, the interface of the transmitter's high-frequency module needs to support CRSF signal output. Taking the EdgeTX transmitter system as an example, we will explain how to configure the transmitter to output CRSF signals and control the transmitter using Lua scripts.
In the EdgeTX system, navigate to MODEL SEL and enter the SETUP menu. Disable Internal RF (set to OFF), enable External RF, and set the Output Mode to CRSF, as shown in the picture below.
Lua scripting is a lightweight and compact scripting language that can be embedded in the transmitter for convenient access to and modification of the transmitter's configuration.
SuperG Nano Transmitter reserves 2 buttons that can be customized by users. Here are the specific steps to operate:
Currently, there are 6 available functions that can be assigned to shortcut buttons. There are 2 ways to use the buttons: long-press and short-press. The duration of a long press can be customized, while the number of presses for a short press can also be customized.
The following are the 6 functions that can be set:Unused | VTX Setting |
Increase Output Power | Enable WiFi |
Enter VTX Channel | Enter Binding Mode |
Enter VTX Band |
The pictures below show the functionality of the transmitter in its factory default settings. (The left button is Button1 and the right button is Button2).
Button | Action | Press | Count |
Button1 (Left Button) |
Enter Binding Mode | Short Press | 3 Times |
Increase Power | Long Press | For 0.5 seconds | |
Button2 (Right Button) |
Go to VTX Channel Menu |
Short Press | 2 Times |
Send VTX Settings | Long Press | For 0.5 seconds |
The SuperG Nano Transmitter utilizes the default firmware, which employs the ExpressLRS V3.3.0 official protocol without a Binding Phrase. Consequently, the binding receiver should also be equipped with firmware V3.0.0 or higher and have no Binding Phrase set. For optimal performance, it is recommended to position the transmitter's two antennas as far apart as possible.
Note: If the firmware of the TX is reflashed and the Binding Phrase is configured, you cannot enter the Binding state through the above method. Please set the RX to the same frequency Binding Phrase, and the TX and RX can be connected automatically.
When the dual transmit power exceeds 500mW, the SuperG Nano Transmitter exhibits relatively high power consumption, leading to a reduced battery life. To prolong the transmitter's usage time, it is advisable to utilize an external battery as a power source.
Note: When the voltage of the radio transmitter battery or external battery is lower than 7V (2S) or 10.5V (3S), please use the Gemini mode of 500mW and 1W carefully, otherwise the transmitter will enter the restart state due to insufficient power supply, resulting in disconnection out of control.
