Make your Internet of Things device cable-free by adding WiFi. Take advantage of the Raspberry Pi and Beagle Bone's USB port to add a low cost, but high-reliability wireless link. Adafruit tried half a dozen modules to find one that works well with the Pi and Bone without the need of recompiling any kernels: its supported by the Bone's Angstrom/Debian installation that comes with each Bone as well as Raspbian and just about any other modern Pi operating system. You'll have wireless Internet in 10 minutes! Works great with 802.11b/g/n networks.

If using with a Beagle Bone: Because of the high power required by WiFi, a 5V 2A power adapter is required to power both the Bone and WiFi. Flaky behavior and crashes may result if this is not followed! Adafruit have a tutorial for using this module with the Beagle Bone!

If using with a Raspberry Pi: The latest Raspbian distributions support this module out-of-the-box. Check out Adafruit's 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. For installation projects or large-scale distribution, Adafruit strongly recommend upgrading to this stick with a larger antenna - especially if you plan on putting the Pi behind something or inside an enclosure/wall/box/sign/etc!

The WiFi module may look slightly different than above, but all modules shipped contain the same chipset and have equivalent performance, the only difference is the plastic shell and any printing. Adafruit have requested to minimize packaging and now ship without a CD since all modern computers have support built in. If you need drivers, see the Technical Details tab
