What Are the COM Express Module Types?

COM Express is a PICMG standard for computer-on-modules, and its pin-out types define which interfaces a module provides. Type 6 is the most common, with display outputs, USB and PCIe for general embedded systems. Type 7 is headless, with multiple 10GbE ports for server-class edge use. Type 10 is a smaller, lower-power pin-out for Mini modules.

The Short Answer

The module carries the processor and memory, and plugs into a carrier board designed for the product, which provides the connectors and any custom I/O. Because the pin-out is standard, a newer module of the same type can usually replace an older one on the same carrier, upgrading performance without redesigning the system.

  • //
    Type 6 Machines with screens, cameras and general I/O.
  • //
    Type 7 Networking and edge server workloads without displays.
  • //
    Type 10 Small, low-power devices.
  • //
    Form factor Compact and Basic balance size against room for processor and memory.
