Kontron COMe Starterkit Eval T2 - Manual (Page 8)

Preface
1. Preface
1.1. 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.
1.2. Intended Audience
This design guide is intended for electronics engineers and PCB layout engineers designing
Carrier Boards for PICMG COM Express Modules.
1.3. No special word usage
Unlike a PICMG specification, which assigns special meanings to certain words such as ”shall”,
“should” and “may”, there is no such usage in this document. That is because this document is
not a specification; it is a non-normative design guide.
1.4. No statements of compliance
As this document is not a specification but a set of guidelines, there should not be any
statements of compliance made with reference to this document.
1.5. Correctness Disclaimer
The schematic examples given in this document are believed to be correct but no guarantee is
given. In most cases, the examples come from designs that have been built and tested.
