COM Express® Benefits
COM Express® modules are compact and highly integrated computers. All modules feature a standardized form
factor and connector layout which carry a specified set of signals. Each COM is based on the COM Express®
specification. This standardization allows designers to create a single-system baseboard that can accept present and
future COM Express® modules.
The baseboard designer can optimize exactly how each of these functions implements physically. Designers can
place connectors precisely where needed for the application on a baseboard designed to optimally fit a system’s
packaging.
A single baseboard design can use a range of COM Express® modules with different sizes and pin-outs. This flexibility
can differentiate products at various price/performance points. The modularity of a COM Express® solution also
ensures against obsolescence when computer technology evolves. A properly designed COM Express® baseboard can
work with several successive generations of COM Express® modules.
A COM Express® baseboard design has many advantages of a customized computer-board design and, additionally,
delivers better obsolescence protection, heavily reduced engineering effort, and faster time to market.
