ITX Motherboards

Mini-ITX Motherboards for Industrial Applications

What Is a Mini-ITX Motherboard?

Mini-ITX is a compact motherboard standard measuring just 170 x 170 mm, providing a complete computing platform with PCIe expansion capability in a space-efficient footprint. Developed for applications where size constraints matter but expansion capability cannot be sacrificed, Mini-ITX boards bridge the gap between ultra-compact embedded boards and full-size ATX motherboards.

Industrial Mini-ITX motherboards from Axiomtek deliver the reliability, extended temperature support, and long-term availability that commercial applications demand. Unlike consumer Mini-ITX boards designed for gaming or home theater PCs, these industrial platforms are built for 24/7 operation in kiosks, automation controllers, medical devices, and edge computing deployments.

Our selection includes Mini-ITX boards spanning entry-level Celeron through high-performance 14th Gen Intel Core i9 processors, ensuring the right performance tier for every application.

ITX Form Factor Family

The ITX family includes multiple form factors at decreasing sizes:

Mini-ITX (170 x 170 mm)

The most common ITX variant, Mini-ITX, provides a full PCIe x16 slot for GPU or accelerator cards while maintaining a compact footprint. Mini-ITX boards fit standard Mini-ITX cases and many compact industrial chassis, making them versatile for a wide range of embedded applications.

Nano-ITX (120 x 120 mm)

Smaller than Mini-ITX, Nano-ITX boards like the NANO840 sacrifice the PCIe slot for an even more compact form factor. Nano-ITX suits applications where expansion is handled through M.2 or Mini PCIe slots and maximum compactness is required.

Pico-ITX (100 x 72 mm)

The smallest ITX variant, Pico-ITX boards, provide basic computing in an extremely compact footprint for deeply embedded applications where board area is severely constrained.

For applications requiring even smaller footprints without PCIe expansion, consider 3.5-inch embedded boards (146 x 102 mm) or Qseven modules (70 x 70 mm).

Key Features

PCIe Expansion

Unlike smaller embedded boards, Mini-ITX motherboards include a full PCIe slot for discrete graphics cards, AI accelerators, or specialized I/O cards. The latest boards, such as the MANO560 and MANO561, feature PCIe Gen4 x16 slots, delivering twice the bandwidth of Gen3 for demanding GPU workloads.

This expansion capability makes Mini-ITX ideal for applications requiring:

• Discrete GPU for machine vision or AI inference
• Frame grabber cards for industrial imaging
• High-performance NVMe storage via PCIe adapter
• Specialized industrial I/O cards

Multi-Display Support

Industrial Mini-ITX boards support multiple simultaneous displays through integrated Intel graphics:

• Triple display: Most models support three independent displays via combinations of HDMI, DisplayPort, VGA, and LVDS
• Quad display: Select models like the MANO500 support four displays through HDMI, VGA, DisplayPort, and LVDS/eDP
• 4K resolution: Intel UHD Graphics on current-generation boards support 4K output for high-resolution HMI and signage applications

The MANO560 and MANO561 feature Intel UHD Graphics 770 with Intel Xe architecture, providing up to 32 graphics execution units for enhanced visual performance without a discrete GPU.

Wireless Connectivity

Modern industrial Mini-ITX boards provide multiple options for wireless integration:

• M.2 Key E: Wi-Fi 6 and Bluetooth modules
• M.2 Key B: 5G, LTE, and 4G cellular modems (3042/3052 form factors)
• Mini PCIe: Legacy wireless cards and additional expansion

The MANO560 and MANO561 include both M.2 Key E and M.2 Key B slots, enabling simultaneous Wi-Fi and cellular connectivity for IoT gateway and edge computing applications.

Security Features

Industrial deployments require hardware-based security. Current Mini-ITX boards include:

• TPM 2.0: Trusted Platform Module for secure boot, disk encryption, and credential storage (onboard on MANO560, MANO561)
• Watchdog timer: Automatic system recovery from software faults
• Hardware monitoring: Temperature and voltage monitoring for predictive maintenance

Industrial Operating Range

Industrial Mini-ITX boards operate across extended temperature ranges, typically 0°C to 60°C, enabling deployment in factory environments, outdoor enclosures, and vehicles where consumer boards would fail. Wide-temperature variants extend this range further for extreme environment applications.

Processor Options

Mini-ITX motherboards support Intel processors from entry-level to high-performance:

Intel Celeron (Soldered): Entry-level processors like the Celeron J1900 (MANO842) and Celeron N3350 (MANO311) provide fanless-capable, low-power computing for basic embedded applications. These boards are ideal for cost-sensitive deployments with moderate processing requirements.

Intel Celeron/Pentium (Socketed): Socketed Celeron and Pentium processors on boards like the MANO560 provide a cost-effective option with upgrade flexibility. The same board can be configured with a Celeron for basic applications or upgraded to a Core i9 for demanding workloads.

Intel Core i3/i5/i7 (8th-10th Gen): Mid-generation Core processors on boards like the MANO521 (8th/9th Gen) and MANO540 (10th Gen) provide strong performance for established applications with proven platform stability.

Intel Core i3/i5/i7/i9 (12th-14th Gen): The latest Core processors on the MANO560 and MANO561 deliver cutting-edge performance with Intel's hybrid architecture. The 14th Gen Core i9 provides up to 24 cores, 32 threads, and 5.8 GHz turbo frequency for demanding edge computing, AI inference, and industrial automation workloads.

Applications

Mini-ITX motherboards power compact yet capable systems across industries:

Kiosks and Self-Service Terminals: Interactive kiosks, ticketing systems, and self-checkout terminals requiring multi-display output, peripheral connectivity, and reliable 24/7 operation in public environments.

Point-of-Sale (POS): Retail POS systems, restaurant order terminals, and payment processing stations requiring compact size, multiple peripherals, and transaction security.

Digital Signage: Media players and information displays requiring 4K output, network connectivity, and fanless operation for noise-sensitive environments.

Factory Automation: Compact industrial PCs for machine control, HMI panels, and production line monitoring. The PCIe slot enables the integration of vision systems for quality inspection applications.

Medical Devices: Diagnostic workstations, patient monitoring, and medical imaging displays requiring long-term component availability, regulatory compliance, and data security (TPM 2.0).

Edge Computing: IoT gateways and edge AI systems requiring GPU acceleration in a compact footprint. The MANO560/561 with PCIe Gen4 x16 accommodates AI accelerator cards for inference workloads.

Gaming and Entertainment: Gaming machines, lottery terminals, and entertainment systems requiring discrete GPU capability in a compact chassis.

For complete Mini-ITX systems, Axiomtek offers the ECM500 industrial chassis, specifically designed for MANO540 and MANO560 boards, providing a ready-to-deploy solution that shortens time-to-market.

Comparing Mini-ITX to Other Form Factors

Choose Mini-ITX when your application requires PCIe expansion capability (GPU, accelerator, frame grabber) in a compact footprint. For applications that do not require PCIe expansion, 3.5-inch embedded boards offer a more compact option. For applications requiring multiple expansion slots or server-grade processors, consider industrial ATX motherboards.
