Product 3/13

BETAFPV Micro RF TX module is based on the ExpressLRS project, an open-source RC link for RC applications.
xpressLRS 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.

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.

BETAFPV Micro TX Module ELRS V2.0.0 firmware is published. The firmware does not include the Binding Phrase. So please make sure the receiver works on officially major release V2.0.0 protocol and no Binding Phrase set.

  • Support 5D buttons and the OLED menu with the official ELRS 2.0.0 release.
  • The color of the LED changes automatically according to the system status.
  • Other new and various features are fully synchronized with the official ELRS 2.0.0.
  • When entering OLED menus page with long pressing, the connection between RF TX module and receiver works normally. Please do not change the Pkt Rate, otherwise, you must re-power the receiver.

User manual of How to Flash Firmware of ELRS RX/TX.

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.
