 The CM-i686 module is a tiny single board computer, designed to serve as a building block in embedded applications. The CM-i686 module has all the components needed to run operating systems such as Windows, Linux or VxWorks. Ready packages for these operating systems are available from CompuLab.

The CM-i686 is both small and inexpensive. Its small size allows integration into hand-held and mobile applications, providing a powerful computing core. Its extremely low price makes it an ideal selection for cost-sensitive applications. Based on AMD's GeodeTM architecture, the CM-i686 provides excellent price/functions/performance in comparison with any other PC-compatible embedded system.

The feature set of the CM-i686 module combines a 64-bit CPU/memory architecture, Flash Disk and essential computing peripherals. For embedded applications, the CM-i686 provides a 32-bit PCI bus, 100Mbit Ethernet, serial ports, general purpose I/O lines and many other essential functions.

A latest version of the card - CM-i686-M uses standardized CAMI (CompuLab's Aggregated Module Interface) connectors which allows interchangeability with other CORE modules, enabling the flexibility required in a dynamic market where application requirements can change rapidly.

Software support for the CM-i686 includes ready-to-run packages for:

* Linux
* Windows CE, NT, XP
* VxWorks
* DOS
