The USB-FLEXCOM4 is designed for rugged industrial environments, but is small enough to fit nicely onto any desk or testing station. The serial module conforms to the USB/104 form factor for flexible mounting either in PC/104 or USB/104 stacks. The USB device is available either packaged in a small, rugged, industrial enclosure or as an OEM board (no enclosure). The USB-FLEXCOM4 is available now for $254.00.
