If nothing else, Adlink's new Express-ATC provides an object lesson in how rapidly computing devices continue to shrink, since it offers substantially the same functionality as the company's
Express-AT, a COM Express Type 2 board the company released just last November. The Express-AT (below left) has the same Intel Atom
N270 processor, 945GSE northbridge, and ICH7-M southbridge, but measures 4.9 x 3.7 inches (125 x 95mm), whereas the Express-ATC (below right) comes in the 3.7 x 3.7 (95 x 95mm)
COM Express Compact format.

According to Adlink, the Express-ATC offers three PCI Express x1 lanes, and is optionally available with 4 x1 lanes (also configurable as 1 x4). Other expansion buses include 32-bit PCI, LPC, SmBus, I2C, and SDVO (serial digital video output), the company says.
The Express-ATC has two SATA-150 ports, IDE (PATA), eight USB 2.0 ports, and gigabit Ethernet, the company says. Analog CRTs with resolutions up to 1600 x 1200 pixels, single or dual LVDS-interfaced displays, and NTSC/PAL HDTV output are all supported, Adlink adds.
A single DIMM socket on the Express-ATC can accept up to 2GB of DDR2 memory, the maximum supported by its chipset, and the module is optionally available with an IDE-based SSD (solid state drive) in capacities from 1GB to 8GB, says Adlink. Operating system support is said to include Windows XP, Windows CE, Windows Vista, and Linux 2.6.
