5.2 Carrier Board Design Guide

The PICMG COM Express Carrier Design Guide is a
150-page document that provides information for
designing a custom carrier board for COM Express
modules. The design guide includes reference
schematics for the external circuitry required to
implement the various COM Express peripheral
functions, explains how to extend the supported buses,
and how to add additional peripherals and expansion
slots to a COM Express-based system
