[Introduction]：EWD95M-433C30 (485) is a high-speed continuous transmission wireless module digital radio, which works in the 410～441MHz frequency band (default 433MHz), and supports intercommunication with our E610 series modules. The radio provides a transparent RS485/RS232 interface, adopts a plastic shell, a guide rail installation structure, and supports 8～28V (DC) wide voltage input. The product is sprayed with three anti-paint, with "anti-mildew", "anti-humidity", "anti-salt spray" and other functions.
