Arduino MKR 485 Shield
Arduino MKR 485 Shield, 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 of the industrial systems that using 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 (like machinery, heating systems, and conveyors) can to turned into IoT devices through a serial connection using the MKR 485. The shield is based on the MAXIM MAX3157 (.pdf datasheet) and provides Half / Full Duplex. Standard operational mode: Half Duplex Specifications Protocol: CAN Bus Interface: Serial Circuit Operating Voltage: 3.3 V Transceiver: MAXIM MAX3157 Buck converter: Texas Instruments TPS54232 (.pdf datasheet) Vin (screw connector): 7 V - 24 V Vin (header): 5 V Compatibility: MKR size; Switchable onboard termination resistor Operating mode: Isolated Half / full duplex (switchable) Resources & Downloads Schematic (.pdf) EAGLE files (.zip)
