COM Express

COM Express® defines a family of Small Form Factor (SFF) and Computer-On-Module (COM) embedded modules for commercial and mil/aero applications. It supports the latest chipsets and serial protocols, including PCI Express Gen 3, 10 Gb Ethernet, SATA, USB 3.0, and high-resolution video. A COM integrates the core functions of a motherboard on a single module. Since 2005, the standard has been widely adopted and is the dominant COM standard for high-performance x86 CPUs. Recommended module types for new designs are type 6, type 7, and type 10. COM Express is managed by PICMG; the carrier board design guide is free, while the full module specification must be purchased.
