So we create this RS485 Arduino shield, especially designed for the Arduino controller board. It converts UART\/Serial protocol to RS485 protocol. This RS485 board allows Arduino access to industrial standard protocol easily.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan style=\"line-height: 17.1428px;\"\u003eIn contrast to RS-422, which has a single driver circuit which cannot be switched off, RS-485 drivers use three-state logic allowing individual transmitters to be deactivated. This allows RS-485 to implement linear bus topologies using only two wires. The equipment located along a set of RS-485 wires are interchangeably called nodes, stations or devices.\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003eIntegrated a standard RS485 port, a mini RS485 port, RS485 headers\u003c\/li\u003e\n\u003cli\u003eProvide the welding areas to make full use of the free space.

It offers data transmission speeds of 35 Mbit\/s for distandances up to 10 m and 100 kbit\/s up to 1200 m. Since it uses a differential balanced line over twisted pair (like RS-422), it can span relatively large distances up to 1,200 m (4,000 ft). A rule of thumb is that the speed in bit\/s multiplied by the length in meters should not exceed 108. Thus a 50 meter cable should not signal faster than 2 Mbit\/s.\" From Wiki.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\n\u003c\/div\u003e \u003ch2\u003e Specification\n\u003c\/h2\u003e \u003cdiv class=\"desCon\"\u003e\n\u003cul\u003e\n\u003cli\u003ePower module: +5V\u003c\/li\u003e\n\u003cli\u003eModule size: 55mmx53mm(2.16\"x2.08\")\u003c\/li\u003e\n\u003cli\u003e16 digital IO port (including a I2C interface)\u003c\/li\u003e\n\u003cli\u003e6 analog IO port and power\u003c\/li\u003e\n\u003cli\u003eOperation and programming mode switch\u003c\/li\u003e\n\u003cli\u003eAutomatic and manual transceiver mode switch (When in manual transceiver mode, the enable end is the 2nd digital IO port)\u003c\/li\u003e\n\u003cli\u003eTransceiver indicating LED\u003c\/li\u003e\n\u003cli\u003eStandard RS485 interface, mini RS485 interface and RS485 pins\u003c\/li\u003e\n\u003cli\u003eWelding area\u003c\/li\u003e\n\u003cli\u003eReset switch\u003c\/li\u003e\n\u003cli\u003ePH2.0 sensor interface for DFRobot RS485 series sensor: URM04 Ultrasonic sensor\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\n\u003c\/div\u003e \u003ch2\u003e Documents\n\u003c\/h2\u003e \u003cdiv class=\"desCon\"\u003e\n\u003cul\u003e\n\u003cli\u003eWiki (Arduino RS485 Shield)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e \u003ch2\u003e Shipping List\n\u003c\/h2\u003e \u003cdiv class=\"desCon\"\u003e\n\u003cul\u003e\n\u003cli\u003eRS485 arduino shield x1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e \u003c\/div\u003e","brand":"DFRobot","offers":[{"title":"Default Title","offer_id":48623711748314,"sku":"tyc1789676593597","price":9.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0824\/8318\/3834\/files\/rs485-shield-for-arduino_1.jpg?v=1789676597","url":"https:\/\/memoryfoamwear.shop\/products\/rs485-shield-for-arduino","provider":"My Store","version":"1.0","type":"link"}
