Multi-Protocol Industrial Edge Router
Build a Multi-Protocol Industrial Edge Router with Arduino Portenta X8
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Bridge brownfield factory devices to modern digital architectures. The Arduino Portenta X8’s Linux core runs Node-RED to translate between Modbus RTU, OPC-UA, and MQTT simultaneously, while the Cortex-M4 microcontroller handles deterministic, real-time RS485 polling. Deploy your own protocol gateway that connects legacy PLCs and sensors directly to SCADA dashboards and cloud IoT platforms.
What You'll Build
A DIN rail-mounted industrial edge router. It polls multiple Modbus RTU slaves over two independent RS485 buses, exposes data through an OPC-UA server, and publishes selected tags to an MQTT broker. Node-RED flows on the Portenta X8 give you a visual, low-code UI to map register addresses, scale values, and add business logic. The end result is a production-ready gateway that slots straight into Industry 4.0 and digital twin projects.
What You'll Learn
- Configuring Node-RED on a Linux-based System-on-Module to run protocol translation pipelines
- Implementing real-time Modbus RTU master polling on an ARM Cortex-M4 with sub-millisecond timing
- Terminating RS485 networks correctly using bias and termination resistors for noise-immune communication
- Deploying an OPC-UA server and MQTT client as a unified industrial data layer

Who This Kit Is For
This advanced kit is built for professional engineers, system integrators, and IoT developers across India. It matches the depth required by final-year B.Tech/M.Tech projects in ECE and EEE, Smart India Hackathon teams prototyping factory digitization, and R&D labs working on Industry 4.0 pilots. If you already understand Modbus or have experience with Arduino development boards, this project gives you a ready-to-industrialise edge gateway.
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?
The AI companion provides instant, context-aware troubleshooting. If you need human help, message us on WhatsApp — we'll walk you through the issue.
Can I use this router with SCADA software like Ignition or WinCC?
Absolutely. The OPC-UA server built into the Node-RED flow makes the router compatible with any OPC-UA client, including Ignition, WinCC, and open-source solutions like Prosys or FreeOpcUa.
Does this kit include everything needed for a DIN rail installation?
Yes, the DIN rail enclosure is part of the kit. All you need to supply is the rail itself and your own RS485 Modbus slave devices.
What programming tools are required?
Node-RED runs in a browser—just connect to the Portenta X8’s IP. The real-time M4 core uses a pre-written Arduino sketch template that you access through the AI companion; only minimal tweaking is needed.
X8 runs Node-RED translating Modbus RTU + OPC-UA + MQTT simultaneously. M4 handles real-time RS485 polling.
