This cute little dongle is perfect for making your Raspberry Pi cable-free by adding WiFi. Take advantage of the Raspberry Pi's USB port to add a low cost, but high-reliability wireless link. You'll have wireless Internet in 10 minutes! Works great with 802.11b/g/n networks.
This module is supported by Windows 10 IoT (october 2015 release or later) - available now on windowsondevices.com. We recommend it for people who plan to be using Windows 10 IoT on the Raspberry Pi or when you know for sure you are going to be using Raspbian Jessie with a current kernel and don't need any kernel modifications because this chipset was only supported recently.
When using with a Raspberry Pi: Check out our detailed tutorial for how to set up WiFi networking on the Pi If you have a model B you may find that you need to have a powered hub to use this adapter, so if you're having power flakiness with your Pi, try a hub!
Please note: These are good for home/office usage with a Raspberry Pi when the router is nearby.
