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.  

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.

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.

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

When establishing a link, it is not possible to enter the LUA script. 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. 

If your radio transmitter is unable to use the F1000 Packet rate or prompts "Baud rate is too low".

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. 

When the F1000 is turned on, the Packet rate between the radio transmitter and the SuperG Nano Transmitter is less than 1000.
