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 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.
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:

Cooling System Iteration
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.
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.

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.
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.
Basic Configuration
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.
- Download the elrsV3.lua script from the BETAFPV Support Center or ExpressLRS Configurator.
- Copy the official Lua script, elrsV3.lua, to the SD card of the transmitter, under the path Scripts/Tools.
- On the EdgeTX system, long-press the SYS button or MENU button to access the SD-HC CARD menu.
- In this menu, select the elrsV3.Lua script and run it.
- If the Lua script runs successfully, the interface will appear as shown in the illustration below.

Custom Buttons
SuperG Nano Transmitter reserves 2 buttons that can be customized by users. Here are the specific steps to operate:
- Enable the transmitter's WiFi or power it on and wait for 60 seconds to enter WiFi mode using LUA programming.
- The RGB indicator light will slowly flash in green, indicating that the transmitter has automatically enabled WiFi (WiFi name: ExpressLRS TX, WiFi password: expresslrs).
- Connect your smartphone or computer to the WiFi network and open a web browser. Enter http://10.0.0.1 to access the custom button settings page.
- In the corresponding button's Action column, select the desired custom function. Then, choose the button type and the number of presses or duration in the Press and Count columns. Click SAVE to complete the settings.
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 |
Bind & External Power Supply
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.
- Put the receiver in a bound state and wait for connection.
- Click the "Bind" in the Lua script or the set custom button to enter the binding mode.
- If the Indicator has turned solid, it indicates that the device has been bound successfully.

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.
- The power consumption of the transmitter is not only related to the transmit power but also to the telemetry ratio. When using high power of 500mW and above, the return ratio can be set higher to reduce power consumption and extend use time.
- For example, in Gemini mode, the power consumption of setting the return ratio to 1:128 is 1000mA, while the power consumption of setting the return ratio to 1:2 is only half of 1:128.

FAQ
- The ELRS LUA script version is outdated and requires an upgrade to elrsV3.lua.
- The baud rate of the radio transmitter is set below 400K, and it should be adjusted to a value above that.
- If there is no option to modify the baud rate, it is necessary to update the radio transmitter firmware, ensuring that EdgeTX is at version V2.7.0 or newer.

- Reason: F1000 requires a baud rate higher than 400K, and the radio transmitter's baud rate is 400K by default.
- Solution: First update the baud rate (greater than 400K) setting in the Hardware from the Model Setup menu or System menu, then restart the radio transmitter to ensure the baud rate setting has been applied. Then change the Packet rate.

- Reason: EdgeTX version problem
- Solution: The EdgeTX version needs to be upgraded to 2.8.0 or above. And the LiteRadio 3 Pro Radio Transmitter defaults to EdgeTX 2.8.0 and does not have this problem.

I Sometimes think that the Transmitter is overheating but it worked perfectly so far
Ottima trasmittente molto performante. Ho notato che il modulo in alluminio riscalda abbastanza però non ho avuto problemi di funzionamento complessivo.
Tested - works good and far.
Fan is very quiet
I'v use it with my tbs tango 2 it works fine and now i have 1W crossfire + 2x1W Elrs options in a single transmitter.
It's a great object. I prefer a little form factor. Great alluminium fin.
