BetaFPV ELRS Micro TX Module (for JR/SLIM bay)


While the ELRS Nano TX Module was designed for transmitters with ‘Lite’ bay such as Frsky Taranis X-Lite, Taranis X9D Lite, TBS Tango 2, or Jumper T-lite, the new ELRS Micro TX Module is for larger controllers with JR/SLIM bay (e.g. Frsky Taranis X9D or TBS Mambo).

The ELRS Micro TX module is based on the ExpressLRS project, an open-source wireless radio communication 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 radio links available while still offering long-range performance.

On the front panel, it has a nice status LCD, futuristic RGB LED light and a control 5D button. ExpressLRS uses the Crossfire serial protocol (AKA CRSF protocol) to communicate between the RX module and flight controller.
