ETXexpress modules are highly integrated off-the-shelf building blocks based on a PCI Express bus architecture that plugs into custom made, application-specific carrier boards. ETXexpress modules measure just 95 mm x 125 mm and include generic functions such as video, audio, Ethernet, storage interfaces and USB ports that are needed for most applications. A custom designed carrier board complements the ETXexpress core module with the additional functionality required for specific applications.

ETXexpress, based on PICMG's new COM Express™ specification, is a result of the convergence of the latest technology standards based on serial differential signalling such as PCI Express, USB 2.0, Serial ATA, LVDS and Serial DVO implemented on an extremely compact Computer on Module. Moving from parallel busses such as PCI and IDE to serial busses such as PCI Express is a change the scale of which has not been seen since PCI replaced ISA.
