About this item

The Official Arduino MKR 485 Shield is a specialized expansion board designed to connect the Arduino MKR series development boards to industrial automation systems using the robust RS-485 communication protocol. RS-485 is widely used in industrial environments due to its noise resistance and capability for long-distance serial communication, making this shield an ideal bridge between modern IoT solutions and legacy industrial equipment.This shield supports both Half Duplex and Full Duplex communication modes, with flexible options for biasing, termination, and master/slave configurations. This adaptability ensures compatibility with a broad range of industrial devices such as PLCs (Programmable Logic Controllers), motor drives, HMIs (Human-Machine Interfaces), and other control systems.By integrating the MKR 485 Shield with an MKR board, older industrial machinery—like heating systems, conveyors, and automation lines—can be easily upgraded and connected to the internet, transforming them into smart, IoT-enabled devices. This allows for real-time monitoring, control, and data acquisition, unlocking new efficiencies and capabilities.The MKR 485 Shield is a must-have for developers and engineers aiming to modernize industrial environments while leveraging the compact power and connectivity of the Arduino MKR ecosystem.
