Tiny, low-cost XScale SBC runs Linux
Oct. 07, 2005

CompuLab is shipping a tiny XScale SBC (single-board-computer) priced at $57 in quantities of a thousand. The CM-X270W is based on an Intel processor and multimedia accelerator, includes Debian Linux, and can be configured to order. It is supported by an embedded designer/manufacturer in the UK.

In addition to the CM-X270W, CompuLab offers several other SBCs designed for mezzanine attachment to custom application boards through miniature high-density connectors. For example, its ARMcore GX is based on Intel's PXA255 embedded processor.

The CM-X270W offers advanced graphics capabilities, thanks to an onboard multimedia accelerator from Intel. UK custom embedded engineering and manufacturing house Anders Electronics offers bespoke graphical systems development on the CM-X270W.

CompuLab claims the CM-X270W has a low-power design comprising multiple power domains, with an on-board switching regulator. Power consumption "in full operation" is said to be 2 Watts, even when rendering XGA (1024 x 768) or SXGA (1280 x 1024) video. During sleep mode, the board draws under 3mW, the company claims.

  • PCMCIA / CF
  • SD / MMC
  • Operates from -40C to +85C
  • 2.6 x 2.3 inches (68 x 58 mm)
