The ATX-i686 is a small single board computer with industry standard Mini-ATX form factor. It is implemented by a combination of the CM-i686 module and the ATX baseboard.

Based on AMD's Geode architecture, the ATX-i686 board delivers a price / feature ratio better than any traditional X86-based alternative. The ATX-i686 is especially attractive for applications requiring a combination of low price and low power consumption with features such as USB, Ethernet and LCD Panel interfaces.

The ATX-i686 has industry standard Mini-ATX form factor, providing an attractive alternative to many other ATX cards available in the market. Within CompuLab's product line, the ATX baseboard is also compatible with the CM-X255 and CM-i886 boards, enabling the flexibility required in a dynamic market where application requirements can change rapidly.

ATX-i686 Features

The "ATX Option" column specifies the P/N code of ATX baseboard required to have the particular feature.  The "CM Option" column specifies the P/N code of CM-i686 required to have the particular feature. ATX-i686 content is the combination of features provided by the attached CM-i686 and features implemented on the ATX baseboard itself. To have a particular feature, both CM and ATX options of that feature must be implemented.

"+" means that the feature is always available, regardless of P/N code.
