As we move toward a world of autonomous machines and real-time AI, the "brain" of these systems needs to be more than just powerful—it needs to be resilient. While many organizations start their journey with standard single-board computers (SBCs), the transition to industrial-grade hardware is where long-term success is built.
This guide explores the unique role of the 3.5" SBC form factor in modern industrial design and why choosing a wide-temperature solution is the key to unlocking reliable edge computing.
Moving Beyond the "Lab-Grade" Mentality
In a controlled office or lab, a standard SBC works perfectly. But the industrial edge is different. It’s a world of sub-zero winters, sweltering factory floors, and constant machinery vibration.
A "Standard" SBC is built for comfort. An Industrial Wide-Temperature SBC is built for conflict. According to Premio's Single Board Computer Overview, these boards are specifically designed to withstand deployment in environments that would destroy commercial hardware.

Why the 3.5" Form Factor is the "Goldilocks" of Industrial Design
Engineers often face a choice: go very small (and lose connectivity) or go large (and lose space). The 3.5" SBC has emerged as the "Goldilocks" solution—it’s just the right size.
- Rich I/O in a Small Footprint: It’s small enough to fit inside tight enclosures but large enough to host multiple LAN ports, USB connections, and expansion slots.
- Thermal Efficiency: The surface area of a 3.5" board allows for better heat dissipation, which is critical for fanless designs.
- Standardization: The 146mm x 102mm dimensions make it easy for system builders to swap or upgrade boards without redesigning the entire chassis.
Spotlight: The Premio CT-DAS01 – Powered by Intel® Atom® x7000RE
To understand where the industry is heading, look at the Premio CT-DAS01. This isn't just another motherboard; it’s a purpose-built engine for the next generation of industrial applications.
The CT-DAS01 leverages the Intel® Atom® x7000RE series (Amston Lake), which Intel has specifically engineered for ruggedized edge appliances. As detailed in Intel's Official Product Brief, these processors offer a unique combination of efficiency and power:
- Industrial-Grade AI Acceleration: The series features Intel® Deep Learning Boost (Intel® DL Boost) and support for the OpenVINO™ toolkit, enabling high-performance AI inference directly at the edge.
- Low-Power Efficiency: With a Thermal Design Power (TDP) as low as 6W to 12W, these processors allow for completely fanless, high-uptime operation in challenging environments.
- Edge-Specific Features: Built-in support for Intel® Time-Coordinated Computing (Intel® TCC) and Time-Sensitive Networking (TSN) ensures predictable, smooth operation for latency-sensitive industrial workloads.
What Makes the CT-DAS01 Different?
- True Industrial Range: It is engineered for the full -40°C to 85°C spectrum, ensuring uptime in extreme hot or cold.
- Connectivity at the Edge: With dual 2.5GbE LAN ports, it handles high-bandwidth data from industrial cameras or sensors with ease.
- Modular Flexibility: It features M.2 slots for NVMe storage, 5G connectivity, and AI modules, allowing the system to grow with your needs.
- Power Resilience: Its 9~36V wide voltage input protects the system from the "dirty power" common in vehicles and factories.
The ROI of Reliability: Total Cost of Ownership (TCO)
The most common mistake in industrial procurement is looking only at the "Price per Board." As highlighted in reports on Industrial vs. Commercial Grade Electronics, the true cost of a standard SBC includes:
- Downtime: Every minute a system is offline costs money.
- Truck Rolls: Sending a technician to a remote site to replace a failed board can cost ten times the price of the hardware itself.
- Redesign Costs: If a consumer board goes end-of-life after 18 months, you have to spend weeks re-validating a new model.
Industrial solutions like the CT-DAS01 offer a lower Total Cost of Ownership by providing a stable, 10-year lifecycle and a failure rate that is significantly lower than commercial alternatives.
Conclusion: Future-Proofing Your Edge Strategy
The shift from "standard" to "industrial" isn't just a technical upgrade—it’s a strategic one. By choosing a rugged 3.5" SBC, you are ensuring that your application is ready for the unpredictable reality of the field.
As AI and 5G continue to push more intelligence to the edge, having a foundation like the Premio CT-DAS01 ensures that your "brains" are as tough as your "brawn."
Frequently Asked Questions (FAQ)
1. What is the difference between an SBC and a traditional motherboard?
An SBC (Single Board Computer) contains all the necessary components—CPU, memory, and I/O—on a single circuit board. This makes it more compact and reliable for industrial use than multi-board systems.
2. Why is the Intel® Atom® x7000RE significant for industrial use?
The "RE" series is specifically designed for industrial use, offering enhanced AI capabilities through Intel® DL Boost and support for industrial features like TSN and TCC, which are not standard in consumer processors.
3. Can the CT-DAS01 handle AI workloads?
Yes. Through its integrated Intel® UHD Graphics and built-in AI capabilities like Intel® DL Boost, it can support edge AI inference for tasks like object detection or predictive maintenance.
