GW16083 Expansion Module

An expansion module for adding Copper and Fiber Gigabit Ethernet Ports to any Gateworks Ventana Single Board Computer

The GW16083 is an expansion module for the Gateworks Ventana and Newport family of single board computers. The expansion module adds six GbE Ethernet ports to any single board computer. Four of the ports are configured to support 10BASE-T, 100BASE-TX, and 1000BASE-T copper IEEE standards. The remaining two ports are each automatically configured for either 10BASE-T, 100BASE-TX, and 1000BASE-T copper or for 1000BASE-X fiber. Other members of the Gateworks expansion module family are available with Mini-PCIe sockets and Legacy Mini-PCI sockets.  An ordering option is available for stacking multiple expansion modules on one single board computer.
