The CM-i686M
Computer-on-Module is a tiny
single board computer, designed to serve as a building
block in embedded applications. The CM-i686M 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-i686M 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 processor, the
CM-i686M provides excellent price/functions/performance in comparison with any
other PC-compatible embedded system.
The feature set of the CM-i686M module combines a
64-bit memory architecture, Flash Disk and essential computing peripherals. For embedded
applications, the CM-i686M provides a 32-bit PCI bus, 100Mbit Ethernet,
serial ports, general purpose I/O lines and many
other essential functions.
The standardized CAMI (CompuLab's Aggregated Module Interface)
connectors allow interchangeability with other CompuLab's
Computer-on-Module's,
enabling the flexibility required in a dynamic market where application requirements can change
rapidly.
Software support for
the CM-i686M includes ready-to-run packages for:
* Linux
* Windows CE and XP
* VxWorks
* DOS
