GW16120 Mini-PCIe Power and USB Expansion Card

Provides Additional 3.3V and 5V Power Sources in a Mini-PCIe Form Factor

The GW16120 is a Mini-PCIe expansion adapter that adds power and USB 2.0 host expansion capabilities to any standard Mini-PCIe socket that supports both PCI Express and USB interfaces. Many applications require 3.3V or 5.0V power supplies for running additional peripherals. This adapter provides a convenient and easy way to acquire these voltages. In addition, for Mini-PCIe slots that support USB host signaling, this adapter routes these USB signals out to a convenient connector along with providing 5V for connecting to USB peripheral devices. The optional GW10102 4-pin to USB type A connector cable is available for standard applications. Development power cables are available as GW10123.

*Disclaimer: This card has only been tested on Gateworks Single Board Computers. Gateworks only provides support when used on a Gateworks SBC.*
