ETXexpress Module Overview
All Kontron ETXexpress Modules are based upon the COM Express™ Specification,
which Kontron played the lead role in developing.
The international COM Express™ Specification defines five Module Types (1-5) and two
new form factor sizes:
Š
Basic (95mm x 125mm) Module
Š
Extended (110mm x 155mm) Module
The primary difference between the Basic and Extended Modules is that Extended
Modules have a larger board size and a thermal envelope.
Five Module Pin-out Types (1-5) exist for Basic and Extended modules, each offering
different functionalities. The ETXexpress-WPM is a Type 3 Basic Module. For a
complete explanation of the features, pin-outs and signals of each of the Module Pin-out
Types 1-5, please see the COM Express™ Specification. The COM Express™
Specification is available on the PICMG (PCI Industrial Computer Manufacturers Group)
Web site: www.picmg.org. There is a fee for the document.
