Description: About This Document
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.
