The Microspace/Digital-Logic MSM800SEL is a PC/104-Plus single board computer built for embedded systems requiring low power, compact form factor, and broad OS compatibility. Built around the AMD Geode LX800 processor at 500 MHz, this fanless design consumes 8 W typical and operates from a single 5 VDC supply. The board supports 128 MB to 1024 MB DDR333-RAM and integrates dual RS232C serial ports, 4× USB 2.0, Fast Ethernet, PATA IDE, optional CompactFlash, and video outputs for CRT/LCD displays up to 1920×1440 resolution.
