Happymodel ES24TX SLIM Pro 2.4GHz ExpressLRS TX

Happymodel ES24TX SLIM Pro 2.4GHz ExpressLRS TX is an expansion transmitter module for small Nano radio shafts. The module is compatible with radios with OpenTX or EdgeTX firmware. ExpressLRS (abbreviated ELRS) is an open source project and the transmit and receive modules are produced by multiple manufacturers. Happymodel is one of them. ELRS is currently one of the most advanced RC transmissions. It offers reliable long distance link, high refresh rate up to 500Hz, adjustable power, update via wifi and more. The ELRS at 2.4GHz outperforms conventional RC systems in all respects at the same frequency while maintaining short antennas. 

ELRS has great community support. However, it is an open system that is rapidly evolving and changing. All information about ELRS can be found at here.

The Happymodel ELRS module has both an internal aluminum heat sink and active fan cooling. The module status is indicated by RGB LED. Thanks to the integrated ESP8258 chip, the module supports communication with the ELRS RX Backpack module. A directional Moxon antenna is already included in the package.
