MKR 485 Shield-board

MKR 485 Shield

The MKR 485 Shield makes it possible to communicate with legacy industrial systems that uses the RS-485 protocol. The shield is simply mounted on a MKR family board, easily turning your old local system into a modern IoT system.

The MKR 485 Shield is based on the MAXIM MAX3157 transceiver, which guarantees data rates at up to 250kbps. The shield can be switched from using a half-duplex communication (one direction at a time) or full-duplex (both directions at the same time), which is easily configured by a switch on board the shield. It also features the TPS54232 buck converter from Texas Instruments.
