Multi-Protocol Industrial Edge Router Kit with Arduino Portenta X8: Connect Legacy Modbus RTU to Modern OPC-UA and MQTT
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine a single device that reads multiple Modbus RTU sensors on a factory floor, exposes that data to a SCADA system via OPC-UA, and simultaneously publishes to a cloud dashboard over MQTT—all without a PLC. With this kit, you build precisely that. The Arduino Portenta X8’s dual-core architecture runs Node-RED on Linux to translate across industrial protocols, while the dedicated Arm Cortex-M4 core handles real-time RS485 polling, creating a rugged edge router ready for Industry 4.0 deployment.
What You'll Build
A fully functional DIN rail-mountable edge router that simultaneously bridges Modbus RTU, OPC-UA, and MQTT. Once assembled, you’ll have a device that reads registers from legacy equipment, serves data as an OPC-UA server to existing HMI/SCADA systems, and pushes real-time metrics to cloud platforms like AWS IoT or Azure IoT Hub. The robust 24V power supply and noise-immune PCB design ensure reliable operation on the factory floor.
What You'll Learn
- Configure Node-RED flows with industrial protocol nodes to build multi-protocol data pipelines
- Write and deploy deterministic RS-485 polling firmware on the Portenta’s M4 core with microsecond timing
- Design a reliable 24V to 5V/3.3V power subsystem using the LM2596 buck converter with input filtering
- Troubleshoot protocol translation issues using built-in serial debugging and the AI companion

Who This Kit Is For
This advanced kit is built for B.Tech and M.Tech students in ECE/EEE working on industrial automation or Smart India Hackathon Industry 4.0 challenges. It’s equally valuable for R&D engineers in manufacturing plants looking to connect legacy PLCs to modern dashboards without licensing expensive gateways. Advanced labs at IITs, NITs, VIT, and BITS Pilani will find it a ready-made platform for teaching edge computing and protocol interoperability.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to start the AI companion trained on this router’s exact wiring and Node-RED flows; WhatsApp and email support are also included with your purchase.
Can I interface this with my Siemens or Mitsubishi PLC?
Yes—any PLC that supports standard Modbus RTU over RS485 can be read by the M4 core. Node-RED also offers contrib nodes for specific PLC brands if you need higher-level protocol support.
Does the router need an internet connection to work?
For local OPC-UA and Modbus bridging, no internet is required. Cloud MQTT publishing requires a wired Ethernet connection, which the Max Carrier provides.
Why are there two RS485 transceivers?
You can split Modbus polling across separate buses or use one for master polling and the other for slave emulation, giving you flexibility to monitor multiple machine networks simultaneously.
X8 runs Node-RED translating Modbus RTU + OPC-UA + MQTT simultaneously. M4 handles real-time RS485 polling.
