Sommaire

Why Form Factor Is the First Decision

The form factor determines the physical size, mounting options, expansion slot count, and power supply compatibility of your embedded system. Choosing the wrong form factor early means costly redesigns later. Match the form factor to your chassis size, expansion requirements, and thermal envelope before evaluating processors.

Industrial Motherboard Form Factor Comparison

Form Factor	Size	PCIe Slots	Best For
3.5" SBC	146 × 102 mm	None (GPIO/PC/104)	Compact embedded, IoT gateway
Pico-ITX (2.5")	100 × 72 mm	1× Mini-PCIe	Ultra-compact, kiosk, medical device
Thin Mini-ITX	170 × 170 mm	1× PCIe x16	Slim Panel PC, compact workstation
Mini-ITX	170 × 170 mm	1× PCIe x16	Box PC, DIN-rail system
Micro-ATX	244 × 244 mm	Up to 4× PCIe	Mid-range automation server
ATX	305 × 244 mm	Up to 7× PCIe	High-expansion server, vision systems

Processor Selection: Low Power vs High Performance

Intel Atom / Celeron N-series, 6 à 10W TDP, passively cooled, sufficient for HMI runtime and IoT gateways
Intel Core i3 / i5 (U-series), 15W TDP, fanless capable, suitable for SCADA workstations and mid-range vision
Intel Core i5 / i7 (H-series), 28 à 45W TDP, active or large passive cooling needed, for AI inference and multi-camera vision
Intel Core Ultra Series 3, integrated NPU, up to 180 TOPS AI performance, ideal for AI-driven automation (e.g., Avalue EMX-PTLP)

Industrial I/O: What to Verify Before You Buy

COM ports, minimum 2× RS-232 for PLC connectivity; RS-422/485 for long-distance or multi-drop networks
LAN ports, dual LAN preferred for OT/IT network separation
GPIO, digital I/O for alarm signals, interlock systems, and external triggers
Wide DC input, 12 à 24V DC input range for compatibility with standard industrial power supplies
TPM 2.0, required for Windows 11 and secure boot in GMP or cybersecurity-conscious applications

Long-Term Availability: The Industrial Advantage

Consumer motherboards are discontinued within 1 à 2 years. Industrial-grade boards from manufacturers like Avalue carry 5 à 7 year product lifecycle guarantees, critical for embedded systems that cannot be re-validated or re-certified every 2 years.

TSL Automation Solutions supplies the full Avalue industrial motherboard range, from 3.5" SBCs to ATX boards, with local India stock, technical support, and after-sales service. Contact us to discuss your embedded project requirements.

Questions fréquentes

Common industrial motherboard form factors are: Mini-ITX (170×170mm) for compact system builds, Thin Mini-ITX for slim enclosures, 3.5-inch SBC (146×102mm) for OEM embedded integration, COM Express (compute-on-module with carrier board) for modular upgradability, and full ATX (305×244mm) for maximum expansion. The right form factor depends on your enclosure size constraints and expansion requirements.

Match the processor to your application: Intel Atom/Celeron N-series (6 à 15W TDP) for IoT gateways, protocol converters, and basic HMI servers; Intel Core i5 (28 à 45W TDP) for SCADA clients, machine vision, and data acquisition; Intel Core i7/i9 or Xeon for AI inference workstations, multi-camera vision systems, and high-tag-count SCADA servers. Always specify the TDP against your thermal design budget for the enclosure.

Key I/O for industrial motherboards: multiple COM ports (RS-232/422/485) for PLC and serial device connectivity, dual LAN ports for OT/IT network separation, PCIe slots for expansion cards (GPU, frame grabbers, fieldbus), M.2 for NVMe storage, USB 3.0 for peripherals, and GPIO for discrete signal interfacing. LVDS or eDP connectors are needed for integrated panel display connections.

Industrial applications run for 5 à 15 years. If the motherboard is discontinued and no replacement or exact spare is available, the entire system may need to be re-engineered when the original board fails. Industrial motherboard vendors like Avalue guarantee 5 à 7 year product lifecycles and extended availability after EOL announcement, critical for long-running factory automation systems.

Yes, TSL Automation Solutions supplies the full Avalue range of industrial motherboards including Mini-ITX, Thin Mini-ITX, ATX, and 3.5-inch SBC form factors. We provide application consultation, processor selection guidance, and full after-sales support in India.
