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: 

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 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.

Express Yourself in Vibrant Colors

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:

1. Enable the transmitter's WiFi or power it on and wait for 60 seconds to enter WiFi mode using LUA programming.
2. The RGB indicator light will slowly flash in green, indicating that the transmitter has automatically enabled WiFi (WiFi name: ExpressLRS TX, WiFi password: expresslrs). 
3. 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.
4. 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: 

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).
