SparkFun According to Pete #54 - How RS-485 Works

Spring is upon us! And with Spring comes… industrial applications? RS-485 is a hard-wired bus architecture that offers a good compromise of data rate and distance, and it can get the job done where you can’t otherwise use WiFi or Bluetooth due to it’s great noise immunity. Capable of point-to-point and multipoint linear networks, RS-485 has been the goto data bus for industrial apps since the late 1990’s. In this episode of ATP, we explore what RS-485 actually is and how it works. So sit back with a coffee and a scone, or maybe a bag of Doritos and some Mountain Dew, and learn yerself something about RS-485!
