COM Express LogoThe COM Express® specification defines a family of Small Form Factor (SFF) and Computer On Module (COM) single board computers appropriate for a wide range of commercial and mil/aero applications. It is designed for the latest chip sets and serial signaling protocols, including PCI Express Gen 3, 10GbE, SATA, USB 3.0, and high resolution video interfaces.

COM Express not only provides the highest performance of the many small form factor standards and products available; it is unique in that it may be used in two ways:

(1) As a standalone single board computer; and
(2) As a processor mezzanine that can be plugged onto a base board, or “carrier” board, that contains the user’s application specific I/O.

Untitled-7-348x232The ability to plug a COM Express module onto a carrier board reduces the time and cost to develop a product, as the user does not need to understand the often complex details associated with high speed signaling or the latest chip sets. The customers’ product lifetime is increased as newer COM Express modules can simply be plugged onto the carrier board to improve performance or lower cost as they become available. This “future proofing” is unique to COM Express in the SFF marketplace.

Revision 3.0 of COM Express provides for the addition of up to four 10 Gigabit Ethernet (10GbE) interfaces on the board.   This new Type 7 connector version of COM Express also increases the number of PCI Express lanes to 32, providing a wealth of connectivity and interface options including the ability to facilitate the use of GPGPUs.

Because SFF applications often need to strike a careful balance between cost and performance, a variety of COM Express form factors and board sizes are defined in the standard.
