Ventana GW16081 Expansion Module

An expansion module for adding Mini-PCIe sockets to any Gateworks Ventana and Newport Single Board Computer

The GW16081 is an expansion module for the Newport and Ventana families of single board computer.  The expansion module adds seven Mini-PCIe sockets to any Ventana single board computer.  Four of the sockets include both PCIe and USB 2.0 signaling and two include SIM sockets for GSM/CDMA modem support.  A highly efficient, wide-input power supply supports high-power Mini-PCIe radios.  Other members of the Ventana expansion module family are available with Legacy Mini-PCI sockets, GbE Ethernet ports, and GbE Fiber Ethernet ports.  An ordering option is available for stacking multiple expansion modules on a single Ventana single board computer.
