2.3 COMe-bCD2 Module Overview
The international COM Express standard defines two new form factor sizes: Basic and Extended. The
primary difference between the Basic and Extended size is a larger board size and thermal envelope in
the Extended size. The COMe-bCD2 follows the basic form factor.
Five module Pin-out Type definitions exist for Basic and Extended modules. Pin-out Types 1-5 apply to
Basic and Extended module form factors. Pin-out Types 1-5 offer different functionalities. For a complete
explanation of the features of each of the Pin-out Types 1-5, please see the COM Express® Specification.
