Description

BETAFPV Micro 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.

The ELRS Micro TX Module Case and Fan are released now! Upgraded module case with 6.5*13.5mm USB port housing is compatible with most USB Type-C cables. Moreover, there are two colors in the new module case. You can make your own module easily.

About the Firmware

The ExpressLRS official project on Github does NOT support the OLED function for the moment. BETAFPV team will work with the ELRS team and make the official repository support the OLED and button function ASAP.

Please get the firmware from BETAFPV Github nowadays until ExpressLRS official support. In BETAFPV branch, the ExpressLRS protocol is V1.1.0 and NO binding phrase for the firmware.

NOTE: There are 2 known issues with this firmware currently. We will solve these 2 issues ASAP. If you find more other issues, feel free to leave a issue here.

  • Only support pressing function for the joystick.
  • When entering OLED menus page with long pressing, the connection between RF TX module and receiver will be lost, the connection will recover after exiting menus page automatically;

You could all use the ELRS offical firmware V2.0-RC2 now, but lost the function of OLED and Joystick. We will work with the ELRS dev team and make the ELRS offical firmware support the full function of the Micro TX Module. For the milestone, OLED will be supported in the V2.1 offically.

How do I set a binding phrase on this Micro TX module when the ELRS offical mainstream does not support OLED yet?

First, download the source code of master-betafpv-oled-menu branch to local from Github.

Second, open the ExpressLRS Configurator and load the upzip source code from local. Select the target device "BETAFPV 900/2400 TX Micro". Now, you could setup your own binding phrase and other options as normal.

Third, build & flash.
