2.3 ETX® Benefits
Embedded technology extended (ETX®) modules are very compact (~100mm square, 12mm thick), highly integrated
computers. All ETX® modules feature a standardized form factor and a standardized connector layout that carry a
specified set of signals. This standardization allows designers to create a single-system baseboard that can accept
present and future ETX® modules.
ETX® modules include common personal computer (PC) peripheral functions such as:
» Graphics
» Parallel, Serial, and USB ports
» Keyboard/mouse
» Ethernet
» Sound
» IDE
The baseboard designer can optimize exactly how each of these functions implements physically. Designers can place
connectors precisely where needed for the application on a baseboard designed to optimally fit a system’s packaging.
Peripheral PCI or ISA buses can be implemented directly on the baseboard rather than on mechanically unwieldy
expansion cards. The ability to build a system on a single baseboard using the computer as one plug-in component
simplifies packaging, eliminates cabling, and significantly reduces system-level cost.
A single baseboard design can use a range of ETX® modules. This flexibility can differentiate products at various
price/performance points, or to design future proof systems that have a built-in upgrade path. The modularity of an
ETX® solution also ensures against obsolescence as computer technology evolves. A properly designed ETX®
baseboard can work with several successive generations of ETX® modules.
An ETX® baseboard design has many advantages of a custom, computer-board design but delivers better
obsolescence protection, greatly reduced engineering effort, and faster time to market.
