RS485 is a serial communication link layer protocol based on differential signaling. It resolves the short transmission distance (15m) limitation of the RS-232 protocol and is a widely used link layer protocol for longer-distance data communication in industrial applications. Since it uses a twisted pair to transmit differential signals and operates in half-duplex mode, it requires switching between receive and transmit states.\u003cbr\u003e2. 5V power supply, supports multiple communication bus interfaces.\u003cbr\u003e3. Typical applications: RS485 communication based on 5V systems.\u003cbr\u003e4. Main resources: SP485 \/ MAX485, control interfaces, communication bus interfaces.\u003cbr\u003e5. Highly suitable for Modbus protocol devices, smart home automation, remote sensor networks, and industrial PLC control systems.\u003cbr\u003e\u003cbr\u003e","brand":"GadgetHQ","offers":[{"title":"5V","offer_id":53694558077275,"sku":"TBD06070201","price":20.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1003\/1041\/7755\/files\/TBD06070201.jpg?v=1785464296","url":"https:\/\/www.gadgethq.co\/products\/waveshare-rs485-board-5v-uart-to-rs485-transceiver-communication-module-5v","provider":"GadgetHQ","version":"1.0","type":"link"}
