Introduction
1.1
COM Express™ Concept
COM Express™ is an open industry standard defined specifically for COMs (computer on modules). Its creation makes it possible to smoothly
transition from legacy interfaces to the newest technologies available today.
A Computer On Module integrates all the core components and standard I/O interfaces of a common PC onto an application specific carrier
board. The key advantage of the COM in the embedded computer industries is that all the highly integrated, high speed components such as
CPU, chipsets and memory are combined on a small module form factor for easy adaptation into different applications across multiple market
segments.
COM Express™ modules have standardized form factors and specified pinouts on the two system connectors that remain the same regardless
of the vendor. The COM Express™ module reflects the functional requirements for a wide range of embedded applications. These functions
include, but are not limited to, PCI Express, PCI, Graphics, High Definition Audio, parallel ATA, serial ATA, Gigabit Ethernet and USB ports.
Two ruggedized, shielded connectors provide the carrier board interface and carry all the I/O signals to and from the COM Express™ module.
Carrier board designers can use as little or as many of the I/O interfaces as deemed necessary. The carrier board can therefore provide all
the interface connectors required to attach the system to the application specific peripherals. This versatility allows the designer to create a
dense and optimized package, which results in a more reliable product while simplifying system integration. Most importantly, COM Express™
modules are scalable, which means once an application has been created there is the ability to diversify the product range through the use
of different performance class or form factor size modules. Simply unplug one module and replace it with another; no redesign is necessary.

conga-IT6/COMe
The conga-IT6/COMe carrier board is based on the Mini-ITX form factor and complies with COM Express™ Carrier Design Guide 2.0
specification. The carrier board supports COM Express™ Type 6 compact and basic format modules.
The conga-IT6/COMe provides most of the functional requirements for any application. These functions include, but are not limited to a rich
complement of contemporary high bandwidth serial interfaces such as PCI Express, Serial ATA, USB 3.0, and Gigabit Ethernet.
