[Introduction]：The EWD95M-433C20 (485) is a digital radio based on the Ebyte E610-T series high-speed continuous transmission wireless module. It operates in the 410-441MHz frequency band (default 433MHz). The radio provides a transparent RS485/RS232 interface, features a plastic housing, a DIN-rail mounting structure, and supports a wide voltage input range of 8-28V (DC). In continuous transmission mode, it can perform continuous transmission at different serial port baud rates, and the receiving end has low data output latency, making it suitable for scenarios requiring rapid transmission of large amounts of data. The product is sprayed with a three-conformal coating, offering features such as "anti-mold," "anti-humidity," and "anti-salt spray."
