Longer Range with Stable Link Quality

Nano TX V2 Module is built-in a TCXO (temperature-compensated crystal oscillator). With the high-quality TCXO, it can withstand extreme temperatures with no fear of heat and cold, continuously outputting accurate frequency for long-range flight. Click to learn more about the TCXO. ensuring a super stable yet strong radio link for pilots to fly in any environment that requires extremely stable signals and low latency, including long-range flights, multiplayer flights, and FPV racing. It gives pilots a robust and aggressive flight experience.

T-LED Antenna

The T-LED antenna innovatively integrates LED with the antenna, enabling direct information display on the antenna. When the antenna is successfully connected, the regular flickering indicates the status of signal transmission and reception. The light being on represents signal transmission, while the light being off represents signal reception. The speed of the flickering varies based on the telemetry ratio and packet rate, offering pilots a unique visual experience.

Additionally, it detects the connection status between the antenna and the TX module, preventing damage caused by incorrect usage. The flickering light irregularly during the antenna swinging indicates antenna damage, while flickering irregularly during turning the antenna connector indicates a loose connection in either the antenna or the TX module, requiring replacement.

Note: This T-LED Antenna only lights up on the Nano TX V2 Module. Other antennas like Moxon and Loop can also be used directly on the Nano TX V2 Module(915/868MHz version), but the 2.4GHz version requires an RP-SMA to SMA adapter.

Cooling System

The Nano TX V2 features a fully injection-molded shell with excellent texture. With its optimized internal airflow channel and a heat sink, a high-speed 1804 cooling fan, it effectively dissipates heat even during high power output, ensuring stable link performance. Pilots can fly with confidence and enjoy reliable performance, thanks to this double-checked cooling solution.

Highly Customizable Solution

Backpack, developed by the ExpressLRS team, is an optional module designed for radio transmitters. It provides enhanced flexibility and scalability, empowering pilots to connect external devices such as goggles, the Nano TX V2 Module offers a highly customizable and expandable solution for pilots' varied application scenarios and functional needs. There are two buttons reserved for pilots to customize their functions, empowering pilots to set buttons according to personal usage habits.

Combination with Most Radio TX

The Nano TX V2 Module could be configured via LUA script. EdgeTX V2.8.0 and OpenTX radio transmitter that supports CRSF could be used easily. It is available for popular Nano port TX like BETAFPV LiteRadio 3 Pro, Radiomaster Zorro/Pocket, Jumper T Pro V2/T20, TBS Tango 2, etc., and Radiomaster TX16, Boxer, and Jumper T16/T20, Frsky QX7, X9 when used with a Micro-Nano Module Adapter.

Note: LiteRadio 3 Pro Radio Transmitter cannot support 500mW due to power supply issues.

ELRS Series

The ExpressLRS Series expands its lineup with the addition of the Nano TX V2 Module. To achieve exceptional link quality. 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

In the EdgeTX system, select "MODEL SEL" and enter the "SETUP" interface. In this interface, turn off Internal RF (set to "OFF"), turn on External RF, and set the output mode to CRSF. Connect the module correctly and then the module will function properly. Settings are shown below.

Lua is a lightweight and compact script language. It can be used by being embedded in radio transmitters and easily reading and modifying the parameter set of modules. The directions for using Lua are as below.

• Download the elrsV3.lua on the BETAFPV official website or ExpressLRS configurator

• Save the elrsV3.lua files onto the radio transmitter's SD Card in the Scripts/Tools folder
• Press the "SYS" button or the "Menu" button on the EdgeTX system to access the "Tools" interface where you can choose "ExpressLRS" and run it
• The below images show the Lua script if it runs successfully

Custom Buttons

There are two buttons reserved for users to customize its functions. Operation steps are shown below.

• The TX module is not well connected to the remote control, need to check whether the Nano pin of the remote control and the TX module socket are in good contact
• The version of the ELRS LUA script is too low and needs to be upgraded to elrsV3.lua
• If the baud rate of the remote control is too low, set it to 400K or above (if there is no option to set the baud rate of the remote control, you need to upgrade the firmware of the remote control, e.g., the EdgeTX needs to be V2.8.0 or above)
• Target Name: BETAFPV Nano V2 2.4GHz/915MHz/868MHz TX

• Reason: The problem is caused by the baud rate of the remote control is too low because the F1000 packet rate needs above 400K baud rate support to work
• Solution: You first need to update the baud rate (greater than 400K is fine) setting in the Model Setup menu or System menu->Hardware, and then reboot the remote control to make sure the baud rate setting has been applied

• Reason: This issue is caused by synchronization issues with the remote control system EdgeTX
• Solution: Upgrade the EdgeTX version of the remote control to 2.8.0 or above
