Tech 101

Mini-ITX is a small form factor motherboard designed for compact, low-power computing. Originally developed by VIA Technologies in 2001, it has become the go-to standard for space-constrained systems, including:

Industrial & Embedded PCs – Fanless, compact designs for automation, kiosks, and control systems.
Rugged Computers – Built for extreme environments where space is limited.
Home & Office Builds – Energy-efficient systems with minimal footprint.
Edge Computing & IoT Devices – AI-driven applications running in small enclosures.

Mini-ITX Dimensions

📏 Size: 170mm x 170mm (6.7" x 6.7")
Expansion Slots: 1x PCIe (usually x16)
🔌 RAM Support: Typically 2 slots (up to 64GB DDR4/DDR5)
🔋 Power Efficiency: Lower power consumption compared to larger boards

Mini-ITX strikes a balance between compact size, decent performance, and efficiency, making it ideal for applications where every inch of space counts.

Mini-ITX vs. Micro-ATX vs. ATX: How Do They Compare?

When choosing a motherboard, size impacts expandability, cooling, and overall performance potential. Here’s how Mini-ITX stacks up:
