⚠️ Important Notes
Legacy CPU Platform: This board supports 2nd/3rd Gen Intel® Core™ U-series (Sandy Bridge/Ivy Bridge) socketed CPUs. These are older platforms. Ensure CPU availability and thermal solution (heatsink/fan) compatibility before purchase.
Memory Compatibility: Supports standard 1.5V DDR3 SO-DIMM memory (1333/1600 MHz). DDR3L (1.35V) modules may work due to backwards compatibility but are not the primary specification. For guaranteed stability, use standard DDR3.
Operating System & Driver Support (Key Advantage): A primary benefit of this platform is its excellent support for legacy operating systems like Windows XP and Windows 7, with widely available drivers. This makes it ideal for maintaining or upgrading older systems without re-engineering the software stack.
Storage Interface Speed: The primary SATA interface for 2.5″ drives is SATA 2.0 (3Gbps). The mSATA slot is SATA 3.0 (6Gbps). For optimal storage performance, consider using the mSATA slot.
Cooling Requirement: This board is designed for active cooling. A compatible CPU heatsink and fan must be installed on the socketed processor for reliable operation. Passive cooling is not recommended for most CPU choices.
Serial Port Configuration: The six COM ports default to RS232. The optional RS485 functionality for two ports must be specified at the time of order.
