With this shield, you can now connect your MKR board to any of the industrial systems that use the RS 485 protocol. • The MKR 485 shield is the ultimate expansion that allows MKR boards to connect to almost any legacy industrial system, such as Industrial PLCs, controllers, units and HMI
Older industrial systems (eg, Machinery, heating systems and conveyors) can be converted to IoT Devices through a serial connection using the MKR 485. The shield is based on the MAXIM MAX3157 and provides Half / Full Duplex
