Arduino MKR 485 Shield is designed to allow the Arduino MKR series of development boards to connect to industrial automation systems using the RS 485 protocol. The MKR 485 Shield can also be used to extend the serial wired communication over much a longer range. The MKR 485 Shield supports Half Duplex and Full Duplex, with or without biasing and termination, and master/slave configuration. 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 (e.g., machinery, heating systems, and conveyors) can to turned into IoT devices through a serial connection using the MKR 485.

Arduino MKR 485 Shield Overview
The Arduino MKR 485 Shield is an RS-485 transceiver add-on designed to stack onto any MKR family board, enabling robust industrial-grade serial communication. With support for half- and full-duplex modes, onboard termination and biasing options, it extends wired links over long distances to connect PLCs, drives, HMIs and legacy automation systems.
Key Features of Arduino MKR 485 Shield
- MAXIM MAX3157 transceiver for reliable RS-485 signaling up to 10 Mbps
- Switchable onboard 120 Ω termination resistor and biasing configuration
- Wide input voltage range (7–24 V) via integrated TI TPS54232 buck converter
- Half-duplex and full-duplex operation with master/slave support
- Compact MKR form factor plugs directly onto any Arduino MKR board
- Genuine Arduino module, fast shipping from Zbotic.in
Applications and Use Cases
- Connecting Arduino MKR boards to industrial PLCs for monitoring and control
- Extending sensor networks or meter reading systems over long cable runs
- Integrating legacy conveyor or HVAC controllers into modern IoT gateways
- Building custom RS-485 telemetry links in process automation
- Implementing multi-drop serial topologies for factory data acquisition
How to Use Arduino MKR 485 Shield
Simply mount the MKR 485 Shield onto your MKR board’s header pins, supply 7–24 V to VIN, then link the A/B RS-485 pair to your network. Use Arduino’s Serial1 (or chosen serial port) at matching baud rate, and set the onboard termination and bias jumpers as needed for half- or full-duplex communication.

Frequently Asked Questions
Can I power the MKR 485 Shield directly from the MKR board?
No. The shield requires 7–24 V on its VIN pin to feed the onboard buck converter. Do not draw power from the MKR 3.3 V regulator to avoid overloading.
How do I enable termination on the RS-485 lines?
Use the onboard jumper to switch the 120 Ω termination resistor on or off. For end-of-line devices, place the jumper to terminate; remove it for intermediate nodes.
Does the shield support both half-duplex and full-duplex modes?
Yes. It can operate in two-wire half-duplex or four-wire full-duplex configurations. Configure wiring and bias jumpers accordingly to match your network topology.
