Mouser takes stocks of Arduino MKR Shields
Three shields suitable for industrial communications systems now number among the range of Arduino MKR shields supplied by Mouser Electronics.
The Arduino MKR 485, MKR CAN and MKR ETH are designed to allow the development boards with an MKR form factor to connect to industrial automation and automotive systems using various communication protocols.
The Arduino MKR 485 shield enables engineers to connect their MKR boards to any of the industrial systems that use the RS 485 protocol. This shield can also be used to extend the serial wired communication over a longer range.
The shield supports half duplex and full duplex, with or without biasing and termination, and master/slave configuration. An onboard, three-way DIP switch allows simple configuration.
With the shield, Mouser says that engineers can tap into almost any legacy industrial system, such as industrial PLCs, controllers, drives, and human-machine interfaces. Older industrial systems such as machinery, heating systems, and conveyors can be turned into Internet of Things devices through a serial connection using the shield.
The Arduino MKR CAN shield connects MKR boards to a controller area network (CAN) bus. Based on a Microchip Technology MCP2515 CAN controller with SPI interface, the MKR CAN shield can help simplify interfacing with industrial systems and automotive applications. An onboard switch allows engineers to enable or disable the termination resistor.
This shield also enables engineers to develop applications related to smart vehicles, autonomous cars, and drones and allows development boards to connect directly to industrial-grade sensors, motors and displays.
The Arduino MKR ETH shield enables an MKR board to connect to the internet using Ethernet instead of a wireless connection, which Mouser says enables a faster and more reliable connection in industrial environments.
The shield is based on a WIZnet W5500 embedded Ethernet controller, which supports up to eight simultaneous socket connections and provides an IP stack capable of both TCP and UDP.
In addition to Ethernet connectivity via the Arduino Ethernet 2 library, the shield includes a microSD card slot with the ability to read and write to a microSD card using the Arduino SD library.
