Full-featured tiny computer, based on CompuLab's
SBC-X270
board
|
The ENC-X270 is a tiny computer based on the XScale PXA270 processor. It runs
Windows CE and Linux. The ENC-X270's unique advantages comprise exceptionally
small size, quiet fanless operation and very low power consumption. With a price
as low as $199, it makes an ideal solution for applications such as
point-of-sale, internet kiosks, classroom computers and even specialized
routers.
The ENC-X270's enclosure is made from aluminum, rugged and splash / dust
resistant.

http://www.cirrus.com/en/pubs/proBulletin/EDB9302A-Z_PB.pdf
The Cirrus Logic EDB9302 is used in the " Qwerk" robotics control system, that
in turn is used in the Telepresence Robot Kit called " Terk" developed at
Carnegie Mellon University and Charmed Labs of Austin, Tx. In the Qwerk system
(see reference
http://www.charmedlabs.com/index.php?option=com_content& task=view& id=29
), use is made of the Cirrrus Logic EDB9302 unit running Red Hat Linux version
2.6 and a Xilinx Spartan 3E FPGA. The Telepresence Robot Kits have been
developed by Associate Professor of Robotics Illah Nourbaksh and memebers of his
Community Robotics, Education and Technology Empowerment (" CREATE" ) Lab.
