The Nano TX V2 Module also offers 3 versions: 2.4 GHz with a maximum output power of 1W, and 915/868MHz with a maximum output power of 2W. Featuring an integrated TCXO, it minimizes frequency deviation for stable performance, eliminating signal interference. Experience stronger signals, longer transmission distances, and an expanded radio transmitter range. With these options, pilots can explore and connect with greater freedom in wireless communication.
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.
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.
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.
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.
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.
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.
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.
There are two buttons reserved for users to customize its functions. Operation steps are shown below.
There are six settable shortcut buttons and two ways to use the buttons: long press and short press. The long press can be set to a custom time duration, while the short press can be set to a custom number of presses. Six settable functions are shown below.
| Unused | Send VTX Settings |
| Increase Power Output | Enable WiFi |
| Enter VTX Channel Menu | Enter Binding Mode |
| Enter VTX Frequency Menu |
The default functions of the module are shown below.
| 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 |
Note: This transmitter hardware does not support button RGB lights.
The default firmware of the Nano TX V2 module is ExpressLRS version 3.3.0. There is no Binding Phrase pre-set. Hence Binding with transmitters has to ensure that the receiver is using V3.0.0 above with no binding phrase.
Note: If the transmitter module has been reflashed with a binding phrase, then using the above binding method will not be bound to other devices. Please set the same binding phrase for the receiver to perform automatic binding.
The power consumption of the Nano TX V2 module when using a transmission power of 500mW or above is relatively high, which will shorten the usage time of the remote control. Users can provide power to the module by using an XT30-USB adapter cable to connect to an external battery. The usage method is shown in the following figure.
Note: When the voltage of the remote control battery or external battery is lower than 7V (2S) or 10.5V (3S), please do not use the 500mW and 1W, otherwise the module will be rebooted due to insufficient power supply, resulting in disconnection and loss of control.
1. Unable to enter LUA script, possible reasons are as follows:
2. Packet Rate cannot be set to F1000 or prompt "Baud rate is too low".
3. The packets between the remote control and the TX module are less than 1000, while the F1000 packet rate is turned on.
