Ultra low power PC104 module from Datasound Laboratories has four LAN connections

Using the latest Vortex86DX CPU, the VDX-6356-L4 has two RS232 serial ports, 2 x USB 2.0 ports, and 16 lines of general purpose I/O. In addition to the 256MB of onboard SDRAM and 4MB of SPI Flash, the module has a 44-pin IDE interface for further expansion. A 5V supply feeds the miserly 500mA consumption.

Interconnection is simplified through the clever use of colour coded connectors and the RoHS compliant VDX-6356-L4 incorporates a watchdog timer and has a standard operational temperature range of -20°C to +70°C with wider range options up to -40°C to +85°C.
