20 Mechanical Consideration

20.1 Form Factor

The COM Express specification describes two different sized COM Express modules. The basic module
(125 mm x 95 mm) and the extended module (155 mm x 110 mm). Based on customer demand, many
COM Express module vendors also offer even smaller form factors with backwards compatibility to the
COM Express specification.
