Multi-Protocol Industrial Edge Router Pro
Build a Multi-Protocol Industrial Edge Router with Arduino Portenta X8 — Translate Modbus, OPC-UA, and MQTT in One Device
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 DIN rail unit that polls a dozen Modbus RTU temperature sensors on the factory floor, exposes their values as OPC-UA nodes for your SCADA system, and publishes alerts to an MQTT broker for cloud dashboards — all translated in real time. This kit puts you at the centre of Industry 4.0 by letting you build a rugged, multi-protocol edge router from the ground up using the Arduino Portenta X8 and its unique dual-core architecture.
What You'll Build
You will assemble and program a industrial edge router housed in a DIN rail enclosure. The Portenta X8's Linux core runs Node-RED, where you visually wire flows that ingest Modbus RTU frames via dual MAX485 transceivers, convert register data into OPC-UA server nodes, and forward selected tags over MQTT. Meanwhile, the onboard M4 microcontroller handles deterministic RS485 polling — free from Linux scheduling jitter — so you never miss a sensor reading. The result is a transparent protocol bridge that sits between legacy serial devices and modern IP-based monitoring systems.
What You'll Learn
- Deploy Node-RED on an industrial Linux SOM to orchestrate multi-protocol data pipelines
- Interface RS485 networks using MAX485 transceivers and properly terminate buses with 120Ω resistors
- Translate Modbus RTU register structures into OPC-UA address space and MQTT JSON payloads
- Configure a real-time Arm Cortex-M4 core for cycle-accurate RS485 polling, offloading the Linux SoC

Who This Kit Is For
This kit is built for India's advanced embedded community: B.Tech ECE and EEE final-year students prototyping industry-ready gateways for campus automation, Smart India Hackathon teams tackling Industry 4.0 problem statements, and working engineers in automotive or pharma plants who need a reliable Modbus-to-OPC-UA bridge without waiting for vendor procurement. It is also ideal for ATL Tinkering Lab mentors demonstrating edge computing, and IIT/NIT/VIT/BITS researchers experimenting with real-time industrial data pipelines.
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?
Your AI companion diagnoses common wiring or Node-RED flow issues instantly; you can also share screenshots over WhatsApp and our engineers typically respond within hours.
Can this router handle multiple Modbus RTU slaves on the same RS485 bus?
Yes, the dual MAX485 modules allow you to independently address two separate buses or set up a redundant bus. Node-RED flows include multi-slave polling logic with configurable slave IDs.
Why does the design use both the Linux X8 and the M4 core, instead of just running everything on Linux?
The M4 handles time-critical polling with microsecond precision. Linux alone would introduce variable delays under load, causing missed responses from Modbus slaves. This dual-core approach guarantees deterministic data acquisition.
Do I need prior experience with OPC-UA or Modbus to succeed?
You should be comfortable with basic C++ and networking concepts, but the kit’s Node-RED flows are pre-configured. The build process itself will teach you the protocol specifics as you wire and test each layer.
X8 runs Node-RED translating Modbus RTU + OPC-UA + MQTT simultaneously. M4 handles real-time RS485 polling.
