Win Enterprises has expanded its computer-on-module (COM) product line with the introduction of its first COM Express module. The MB-07315 employs the Intel 945GM chipset, supports both Core 2 Duo and single-core Celeron M processors, and runs Linux, among other embedded OSes.

Equipped with a single SO-DIMM socket, the MB-07315 accepts up to 2GB of 400/533/667 MHz DDR2 memory. Like other COM Express modules, it provides a variety of I/O interfaces, along with PCI and PCI Express expansion buses. I/O includes:

  • Gigabit Ethernet (based on Intel 82573)
  • AC 97 audio
  • 2 x Serial ATA interfaces
  • 8 x USB 2.0 ports
  • 1 x LPC (low pin count) interface
  • I2C bus
  • 8 x GPIO lines
  • PCI bus — 32-bit 33 MHz PCI 2.3
  • PCI Express — choice of:
    • 5 x 1-lane and 1 x 16-lane
    • 1 x 1-lane, 1 x 4-lane, and 1 x 16-lane

The module's maximum video RAM of 64MB can support CRT resolutions up to 2048 x 1536, and LCD resolutions up to 1600 x 1200. Its available video output ports include dual SDVO (serial digital video out), dual 18-bit LVDS (low voltage differential signaling) for flat panels, analog VGA, and TV-out.

According to Win Enterprises, the module complies with the COM Express form-factor “pin-out type II” option. It measures 3.8 x 5 inches (95 x 125mm), and runs from a single +12V DC power source.

In addition to Linux, the module can run Windows XP, Windows XP Embedded, and Windows CE, Win Enterprises said.

Available now, the MB-07315 is priced at $201 for a single unit, with quantity discounts available. An evaluation baseboard is also available.
