For previous order, if you do not have a suitable USB cable for this Micro module, feel free to contact us. Email to firstname.lastname@example.org.
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.

ELRS 2.4G 1W Version:
The black version with maximum 1W RF output power is released now. Support all 5D button dimensions based on BETAFPV ELRS V2.0.0 firmware. A new backpack function is added, allowing wireless communication between ExpressLRS, and other FPV related devices for command and control, or for querying config.
Compared with 500mW versions, it not only builds in a cooling fan but also the heat sink is included, which enhances the performance of cooling. So this module can work properly in daily use and not need to worry about temperature.
Note: Please make sure the VRX also supports backpack function when using the module VRX-backpack function. Backpack function will be added to the 500mW version in the future.
Please assemble the antenna before power on. Otherwise, the PA chip in the Micro TX module will be damaged permanently.
Please DO NOT use 3S or above bettery to power up the TX module via XT30 port. Otherwise, the power supply chip in the TX module will be damaged permanently.
The antenna in the package is not the same as picture show for 915MHz and 868MHz version.
About the Firmware:
The ExpressLRS offical project on Github does NOT support the OLED function for the moment. BETAFPV team has made a pull request on Github and wait for the offical to finish this merge. We will work with the ELRS team and make the offical repository support the OLED and button function ASAP.
Please get the firmware from BETAFPV Github nowadays until ExpressLRS offical support.

Button and OLED:
The ELRS TX module could be configured via the OpenTX LUA script. With OLED and button, no-OpenTX radio controller that supports CRSF could use this ELRS Micro module easily. The following no-OpenTX radio controllers work well with this TX module. Futabas T16IZ, T16SZ and T18SZ (with update to 3.9e), Wsky ET16, Radiolink AT9S Pro.
There is a 5D button on the micro module. Pay attention only the virtical dimention works and the other four dimentions are invalid. Below is the basic operation of the button and OLED.
