This Slim Pro TX module is designed by Happymodel and based on the open-source ExpressLRS which is a very popular low latency and high packet rate RF module for RC airplanes and FPV Racing drones. Its main hardware architecture is ESP32, ESP8285, and SX1280 RF chip. The ES24TX Slim Pro module is a complete solution that is already pre-load the Expresslrs firmware and its plug-and-play for Frsky X-lite/X-lite pro/X9 Lite, TBS Tango2.
This Slim Pro module comes with an aluminum alloy shell and is equipped with a cooling fan that automatically works when the module is working at 250mw.
The slim pro-TX module supports a maximum power output of about 1000mw, this would be very useful for Long Range FPV.
Please note this is for only X-light and Tango2 Transmitters
