The board consumes only 1.4 W and only 200 mW in standby mode. The board has an impressive array of peripherals, including a flat-panel display controller for TFT and STN displays, 10/100BaseT Ethernet, five serial ports, a dual USB host controller, an AC'97 audio/codec, and a CompactFlash interface. It supports up to 64 Mbytes of SDRAM, 16 Mbytes of StrataFlash, and 256 kbytes of battery-backed-up SRAM. A 1-Mbyte boot ROM can load Linux, Windows CE, VxWorks, and QNX Neutrino. Pricing starts at $410.
