BETAFPV ELRS Micro 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.
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.
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.
Below is the diagram for ELRS 2.4G 1W version. DIP switches will be added to 500mW versions in the future.
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.
Note: Please do not turn on all DIP switches at the same time. You can refer to the chart to know about DIP switches on/off based on different uses.
