This document provides information for designing a custom system Carrier Board for COM Express Modules.
It includes reference schematics for the external circuitry required to implement the various COM Express peripheral functions. It also explains how to extend the supported buses and how to add additional peripherals and expansion slots to a COM Express based system. It's strongly recommended to use the latest COM Express specification and the Module vendors' product manuals as a reference.
This design guide is not a specification. It contains additional detail information but does not replace the PICMG COM Express (COM.0) specification. For complete guidelines on the design of COM Express compliant Carrier Boards and systems, refer also to the full specification – do not use this design guide as the only reference for any design decisions.
