This Micro TX is designed by Happymodel and based on the open-source ExpressLRS which is a very popular low latency and high re-flashed rate RF module for RC Airplane and FPV Racing. Its main hardware architecture is ESP32, ESP8285, and the SX1280 RF chip. The ES24TX module is a complete solution that is plug and play and already pre-loaded with Expresslrs firmware.
