Arduino MKR 485 Shield

Want to add serial communications to your device using the RS-485 protocol? The Arduino MKR 485 shield will provide the industrial connectivity you need.

Thanks to this shield, you can now connect your MKR board to any 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, drives, and HMIs. Old industrial systems, such as machinery, heating systems, and conveyors, can be turned into IoT devices through a serial connection using the MKR 485.

The shield is based on the MAXIM MAX3157 and provides half/full duplex communication. The standard operational mode is half duplex.
