Product Details
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.

Diagram
BETAFPV Nano RF module is compatible with the 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.
Upgrade the Firmware
The stock firmware of the Nano receiver and TX module manufactured by our company is ELRS 3.3.0.;
ELRS Innovative team 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.
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. Short and consecutive press 3 times to bind.
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.
| LED Color | RF output power |
| Blue | 100mW |
| Purple | 250mW |
| Red | 500mW |
