BETAFPV ELRS Nano TX Module 2.4G 915MHz 868MHz Nano TX Module for TBS Tango 2 Pro FRSKY X-Lite X9 Lite Long Range Transmitter

BETAFPV Nano RF TX module is based on the ExpressLRS project, an open-source RC link for RC applications. ExpressLRS aims to achieve the best possible link performance in both speeds, latency, and range. This makes ExpressLRS one of the fastest RC links available while still offering long-range performance.

Specification

                                  25Hz/50Hz/150Hz/250Hz/500Hz (2.4GHz)

• RF output power: 100mW/250mW/500mW

• Frequency bands (Nano RF Module 2.4G version): 2.4GHz ISM

• Frequency bands (Nano RF Module 915MHz/868MHz version): 915MHz FCC/868MHz EU

• Input voltage: 5V~12V

• USB port: Type-C

Diagram

BETAFPV Nano RF module is compatible with radio transmitter which has the nano module bay (AKA lite module bay, e.g. Frsky Taranis X-Lite, Frsky Taranis X9D Lite, TBS Tango 2). 

Note：Please assemble the antenna before power on. Otherwise, the PA chip in the Nano TX module will be damaged permanently.  

ExpressLRS uses the Crossfire serial protocol (AKA CRSF protocol) to communicate between the radio transmitter and the Nano TX module. So make sure your radio transmitter supports the CRSF serial protocol. We use the radio transmitter with the OpenTX system to show how to set up the CRSF protocol and LUA script. To set this up, in the OpenTX system, enter into model settings, and on the "MODEL SETUP" tab, turn off the "Internal RF". Next, enable "External RF" and select "CRSF" as the protocol.

ExpressLRS use the OpenTX LUA script to control the TX module, like bind or setup. With the LUA script, pilots could check and set up some configurations of the Nano RF TX module. For more details, please check the Support Page.

• Save the ELRS.lua script files onto the radio transmitter's SD Card in the Scripts/Tools folder;

• Long press the "SYS" button (for RadioMaster T16 or similar radios) or the "Menu" button (for Frsky Taranis X9D or similar radios) to access the Tools Menu where you can find ELRS script ready to run with only one click;

• The below image show, the LUA script run successfully;

Bind & Output Power

Nano TX module could enter binding status via ELRS. Lua script, as described in the "LUA Script" chapter. Besides, a short press button on the module could also enter binding status.

Note: The LED will NOT flash when entering binding status. The module will exit from binding status 5 seconds later auto.

Nano RF TX module could switch the output power via ELRS. Lua script, as described in the "LUA Script" chapter. Besides, long-press the button on the module could switch the output power.

The RF TX module output power and LED indication as shown below.

New adapter with upgrades is released now and is very easy to install. A 3PIN GH1.25 terminal socket, which can be used for Futaba, or other no-OpenTX radio controllers, is added to the bottom of the module adapter.

With the use of micro-nano module adapter, nano tx module can work on transmitters with a Micro port (or JR port) easily. Especially, it supports BETAFPV ELRS Nano TX Module.

Specification

• Item:  Micro-Nano Module Adapter / Micro-Nano Module PCBA

• Size: 65*48*28mm (JR module size）

• Weight: 24.80g

• Input: JR module bay (Micro module bay)

• Output: Nano module bay (Lite module bay)

• Supported radio transmitter: Frsky X9D/X9D Plus/X12S/X10/X10S/X7/X7S, 
  Flysky TH9X, Turnigy 9XR/9XR PRO, FUTABA 16IZ, Jumper T16/T18/T18 Pro, 
  Radiomaster TX16S/TX18S, TBS Mambo

• Supported TX Module: BETAFPV Nano TX Module, TBS Crossfire Nano TX、Frsky XJT Lite/R9M Lite/R9M Lite Pro.

PCBA Only

Compared with the previous version, the appearance of PCBA is modified. 3PIN GH1.25 terminal socket is also added to the boards, which is suitable for other no-OpenTX radio controllers. Besides, the PCBA can be used directly without a case or used with a printed case.

Micro-Nano Module Adapter (PCBA) is available for those who can print the case for themselves. You can download the adapter case STL file on our technical support page.

Note: Please make sure the wiring is correct if the PCBA is used without case.

Supported Radio TX

The module adapter is suitable for transmitters with a Micro port (or JR port). For example, Frsky X9D, FUTABA 16IZ, TBS Mambo, Turnigy 9XR, Jumper T18, etc.
