CompuLab claims that the CM-iGLX is the "smallest Geode LX-based PC-on-module." It targets mobile, industrial, and harsh-environment applications, the company says. The company notes that the module's standardized CAMI ("CompuLab's Aggregated Module Interface") interface connectors enable interchangeability with other of CompuLab's COM modules.

The module's key features and specifications are said to include:

RAM -- 256 MB DDR
Flash -- onboard 128MB to 512MB NAND flash
ATA100 hard drive interface
Video -- controller for up to 1920 x 1440 x 32 bpp @ 85Hz, compatible with LCD and FPM displays
Video input port
Touchscreen Controller
10/100 Mbps Ethernet port
Phillips UCB1400 audio codec, with speaker and microphone support
3 x host USB-2 ports (provide keyboard/mouse support)
2 x serial ports
GPIO -- 4 dedicated and 4 shared lines
General purpose bus and optional PCI, LPC, AC97 busses
Encryption unit -- 128-bit DMA-based crypto acceleration
Size -- 2.7 x 2.3 inches (68 x 58 mm)
Interchangeable with other CompuLab modules via "CAMI" connectors

Linux support

CompuLab offers extensive ready-to-run Linux support for its computer-on-module products, including the CM-iGLX, including OS images that can be loaded directly into the onboard "flash disk." The Linux support package includes 2.4 and 2.6 series kernels, patches, standard utilities (gzip, gunzip, tar, etc.), bash shell, flash disk drivers, drivers for all other peripherals available on the module, networking support (FTP, samba, telnet/ssh), and X-windows, according to the company.

In addition to Linux, the module supports Windows XP/XPe and Windows CE, CompuLab says.

Availability

The CM-iGLX is shipping now, priced around $120 in OEM quantities of 1,000 units, according to CompuLab. Small quantity pricing was not disclosed.

The module is optionally available in an extended temperature version that supports -40 to +85 degrees C..
