About Micro ATX Motherboards

Multi-Slot Expansion in a Compact 244 × 244 mm Platform Portwell industrial Micro-ATX motherboards combine desktop-class processing, multiple expansion slots and industrial I/O within the standard 244 × 244 mm form factor. Designed for systems that require greater expandability than Mini-ITX while occupying less space than full-size ATX, the platform supports high-performance computing and flexible peripheral integration. Standard 244 × 244 mm Micro-ATX form factor Intel® Core™ Ultra Processors (Series 2) DDR5 memory support up to 96GB PCIe Gen 5 x16 and additional PCIe expansion slots M.2 Key M support for storage expansion Dual Gigabit Ethernet with OOB functionality on one port Six COM ports for serial device integration USB 3.2 and SATA III connectivity Dual HDMI® and DisplayPort outputs Onboard TPM 2.0 security Balancing Expansion and System Footprint Micro-ATX is suitable for system designs that require multiple add-in cards but do not need the full expansion capacity of an ATX motherboard. Before selecting the platform, confirm the required PCI Express lane configuration, card dimensions and spacing because the physical connector size may differ from the number of electrically available lanes. System planning should also account for processor TDP, expansion-card power, cooling, chassis clearance and airflow. Review the storage, networking, serial I/O and display requirements together to ensure the selected motherboard and enclosure can support the complete system configuration.
