Arduino becomes compatible with the RS-485 protocol!
Do you want to add serial communication via RS-485 protocol to your device? The Shield MKR 485 provides the industrial connectivity you need.
Arduino® MKR 485
Thanks to this shield you can now connect your MKR board to all industrial systems that use the RS 485 protocol. The Shield MKR 485 is the ultimate expansion that allows MKR boards to connect to almost any legacy industrial system, such as industrial PLCs, controllers, drivers and HMIs. Old industrial systems (e.g. machines, heaters and conveyor belts) can be converted into IoT devices via a serial connection with the MKR 485. The shield is based on the MAXIM MAX3157 and offers half/full duplex. Standard operating mode: half duplex
