Can be utilized as components by plugging into an application-specific baseboard and putting the core CPU and subsystems together with sound, SVGA, Ethernet and additional I/O.

The module connects to the rest of the embedded system through high-density, low profile SMT connectors, which carry both ISA and PCI bus signals as well as dedicated I/O interfaces.

Mechanics of interconnection is physically the same height as a one-board solution.

ETX modules are interchangeable, allowing system designs to be scaleable.

Unique design of LAN placement:
- Avoids unwanted interruption: LAN function on the baseboard- Provides better performance and reliability
- Chip and transformer not affected by noise signals in communication
