Product detailed description
The BETAFPV Micro RF TX module is based on the ExpressLRS project, open-source for RC applications. ExpressLRS aims to achieve the best possible link performance in both speed, latency and range. This makes ExpressLRS one of the fastest RC links available while still offering long range performance.

Diagram
The BETAFPV Micro RF TX module is compatible with a radio transmitter that has a micro module shaft (AKA JR/SLIM module shaft, e.g. Frsky Taranis X9D、TBS Mambo).
Note: Please connect the antenna before turning on. Otherwise, the PA chip in the Micro TX module will be permanently damaged.
Note: DO NOT use 3S or higher to power the TX module through the XT30 port. Otherwise, the power chip in the TX module will be permanently damaged.
The ELRS TX module can be configured using the OpenTX LUA script. With an OLED and button, a radio controller without OpenTX that supports the CRSF protocol could easily use this ELRS Micro module. The following non OpenTX radio drivers work with this TX module: Futaba T16IZ, T16SZ and T18SZ (with update to 3.9e), Wsky ET16, Radiolink AT9S Pro.
Basic configuration
ExpressLRS uses the Crossfire serial protocol (AKA CRSF protocol) to communicate between the radio transmitter and the TX module. So make sure your radio transmitter supports the CRSF serial protocol. We use the OpenTX radio transmitter to demonstrate how to set up the CRSF protocol and the LUA script. To set this up, in the OpenTX system, go to the model settings and under the "MODEL SETUP" tab, turn off "Internal RF". Next, enable "External RF" and select "CRSF" as the protocol.
