The BETAFPV Micro RF TX module is based on the Express LRS project, an open-source RC link. 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.
Note: Please assemble the antenna before power on. Otherwise, the PA chip in the Micro TX module will be damaged permanently.
Note: Please DO NOT use 3S or above battery to power up the TX module via XT30 port. Otherwise, the power supply chip in the TX module will be damaged permanently.
About the firmware
The ExpressLRS offical 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 issue, feel free to leave a issue here.
You could all use the ELRS official 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 official firmware support the full function of the Micro TX Module. For the milestone, OLED will be supported in the V2.1 officially.
