1 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, graphics, high definition audio, 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. The result is a more reliable product with simplified system integration.
Most importantly, COM Express™ modules are scalable. Once an application has been created, the product range can be diversified by using
different performance class or form factor size modules. Simply unplug one module and replace it with another; no redesign is necessary.
1.2 conga-STX7
The conga-STX7 carrier board design is based on Type 7 pinout definition and it complies with COM Express Specification 3.0. The carrier
board comes in Intel Mini-STX form factor and supports COM Express Type 7 compact and basic form-factor modules.
The conga-STX7 provides most of the functional requirements for server application. These functions include, but are not limited to a rich
complement of contemporary high bandwidth interfaces such as PCI Express, Serial ATA, USB 3.0/2.0, and 10 Gb SFP+.
By combining the scalability of COM Express modules, the conga-STX7 carrier board provides manufacturers and developers with a platform
to jump-start the development of systems and applications based on COM Express Type 7 specification. This helps to reduce product design
cycle and encourages rapid innovation in system design, to meet the ever-changing needs of the market.
