ELRS TX400 500-560 MHz Transmitter—
ELRS (ExpressLRS) module for drones – long range, low latency, and reliable communication
The ELRS TX400 500-560 MHz transmitter from [brand] is a modern solution for FPV drone control, combining high performance with a compact form factor. The ExpressLRS (ELRS) system is known for its ability to provide maximum communication range with minimal latency and excellent resistance to electromagnetic interference, making this module an optimal choice for FPV professionals and enthusiasts.
The transmitter kit includes a module and an antenna, allowing for quick integration of the device into your project. The antenna connector is SMA-F, ensuring a reliable mechanical and electrical connection. Dimensions and weight are critical for aircraft: the module size is 75*55*33 mm, the antenna size is 243*153*4 mm, and the kit weight is 55 g, which minimizes the impact on the drone's overall mass and flight characteristics.
