Introduction

EWM293-470T20S/EWM293-470T30S is a new domestically-developed long-range Sub-1G wireless data transmission module, featuring high data rate, long-range transmission, and low cost. The module operates in the 470MHz–510MHz frequency band with a typical transmit power of 20/30dBm, integrating both transmit and receive functions. Users can flexibly configure parameters such as transmit power, operating channel, and serial port baud rate via AT commands. The module provides a UART-based universal AT command interface, enabling users to quickly configure operating frequency, data rate, working mode, and other parameters according to application requirements, thereby achieving wireless data transmission and reception.
