[Introduction]：EWD95M-400GL20 (485) is a wireless data transmission radio based on Ebyte E290-T series serial port module (UART). It adopts ChirpIoT™ spread spectrum technology, has multiple transmission modes, works in the 410.125~493.125MHz frequency band (default 433.125MHz), provides transparent RS485/RS232 interface, adopts plastic shell, guide rail installation structure, and supports 8~28V (DC) wide voltage input. The data transmission radio adopts a new generation of ChirpIoT™ spread spectrum technology, supports half-duplex wireless communication, has high anti-interference and high sensitivity; supports air wake-up, wireless configuration, automatic relay, communication key, AT command, IAP upgrade and other functions, and supports sub-packet length setting.
