RS485 is a serial communication link layer protocol based on differential signal transmission. It resolves the limitation of the RS-232 protocols short transmission distance (15 m) and is a widely adopted link layer protocol for long-distance data communication in industrial environments. Because it utilizes a single twisted pair to transmit differential signals, it operates in half-duplex mode, requiring state switching between receiving and transmitting.\u003cbr\u003e2. 3.3 V power supply, supporting multiple communication bus interfaces.\u003cbr\u003e3. Typical Application: RS485 communication.\u003cbr\u003e4. Main Resources: SP485 \/ MAX485, control interface, communication bus interface.\u003cbr\u003e5. Highly suitable for Modbus protocol devices, smart home automation, remote sensor networks, and industrial PLC control systems.\u003cbr\u003e\u003cbr\u003e","brand":"Infinit Tech","offers":[{"title":"3.3V","offer_id":50586998276235,"sku":"TBD06070092","price":344.45,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/1880\/7435\/files\/TBD06070092.jpg?v=1790972444","url":"https:\/\/infinittech.co.za\/products\/waveshare-rs485-board-3-3v-uart-to-rs485-transceiver-communication-module-3-3v","provider":"Infinit Tech","version":"1.0","type":"link"}
