Description

The Official Arduino MKR 485 Shield is specifically engineered to enable Arduino MKR series development boards to interface with industrial automation systems leveraging the RS485 protocol. This shield is also suitable for extending serial wired communication over significantly longer distances than standard UART connections, making it indispensable for robust industrial applications.

It offers comprehensive support for Half Duplex and Full Duplex communication, including options for biasing and termination, and accommodates both master and slave configurations. The MKR 485 Shield serves as a critical expansion, allowing MKR boards to seamlessly integrate with a wide array of legacy industrial systems such as PLCs, controllers, drives, and Human-Machine Interfaces (HMIs). By facilitating a serial connection via the MKR 485, older industrial assets like machinery, heating systems, and conveyor belts can be effectively transformed into IoT-enabled devices.

Frequently Asked Questions

What Arduino MKR boards are compatible with this shield?

The Arduino MKR 485 Shield ASX00004 is designed for the entire Arduino MKR series, connecting directly to their standard headers. This ensures broad compatibility across various MKR boards for diverse industrial applications, leveraging the compact MKR form factor for seamless integration.

What are the operating modes supported by the RS485 Shield?

The shield supports both Half Duplex and Full Duplex operating modes, with switchable biasing and termination resistors. This flexibility allows it to adapt to various RS485 network configurations, from simple point-to-point links to complex multi-drop systems with ease and reliability.

What is the purpose of the MAXIM MAX3157 transceiver on this shield?

The MAXIM MAX3157 is a robust RS485/RS422 transceiver providing isolated communication, crucial for industrial environments. It protects the MKR board from ground loops and voltage spikes, ensuring reliable data integrity over long cable runs in noisy settings, enhancing system stability.

Can this shield power other devices or is it only for communication?

While primarily for RS485 communication, the shield includes a Texas Instruments TPS54232 buck converter, which can supply stable power to the MKR board itself. It's not designed to power external high-current devices but ensures efficient power management for the communication interface.
