BETAFPV ExpressLRS ELRS 2.4G Nano TX Module 500mW for BetaFPV Lite3/3Pro/Jumper T-Pro/Zorro/TBS Tango2 Remote BT-Nano TX
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.
Packet refresh rate: 25Hz/50Hz/150Hz/250Hz/500Hz (2.4GHz)
RF output power: 100mW/250mW/500mW
RF output power: 0.3mW/Mhz 20mW MAX (Japan MIC version)
Frequency bands (Nano RF Module 2.4G version): 2.4GHz ISM
Input voltage: 5V~12V
USB port: Type-C
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).
Upgrade the Firmware
The stock firmware of the Nano receiver and TX module manufactured by our company is ELRS V1.0.0-RC5 (the fifth release candidate version);
ELRS Innovative team has officially released the first major version V1.0.0 on 17th July. It has some updates :
2.4G Nano TX Module supports 500Hz refresh rate;
Short press the button on the Nano module 3 times to get into the binding status.
High recommend upgrading the TX modules and receivers' to the first major version V1.0.0. Also, pilots could check this Github page for the newest released version if possible.
Now Nano TX module from Jan 2022 supports upgrade via WIFI. For orders before Jan 2022, please contact us at email email@example.com if you have any questions or problems.
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;
