allows fanless operation, making them ideal for industrial applications. The
board is configured with a 733MHz or 1GHz MMXcompatible CPU with up to 512MB of
PC133 SDRAM plus a CompactFlash socket. Also, a 10/100 Ethernet controller, USB
2.0, 4X AGP video with CRT/flat panel/LVDS interfaces, four serial COM
channels, 24 digital I/O lines, AC97 audio, and the standard AT peripheral
feature set are included.<o:p></o:p></span></p>

style='font-size:10.0pt;font-family:Times-Roman'>modules or with two high-speed
USB 2.0 channels. The board will operate from - 40° to +85°C for rugged
applications requiring an embedded PC. Its x86-PC software compatibility
assures a wide range of tools to aid in your application’s program development
and checkout.</span><o:p></o:p></p>
