Name : Cerberus_001

Introduction :
    Cerberus001 is a general purpose network control card which the size is
 very small for mobil use. On board processor is Intel StrongARM SA1110 206M
 Hz with 64 MB SDRAM and 16MB flash. One 10base ethernet controller is
 equipped on board for network. The control card can receive or transmit the
 console data from on board UART and USB. On board LCM and LCD connectors are
 provided for numeric and graphic display. And one IrDA port is provided for
 wireless control. A general purpose I/O controller is also equipped on board
 for system RTC, this controller also provides many general purpose I/Os and
 one full-duplex UART for the on board expansion bus. Cerberus_001 takes AC
 110V to 220V as the power input.
