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 installation that comes with each Bone as well as the Adafruit Occidentalis distribution. 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 has a tutorial for using this module with the Beagle Bone

If using with a Raspberry Pi: The latest Wheezy distributions support this module out-of-the-box. Also, the Adafruit Occidentalis distribution has support built in.Check out Adafruit's detailed tutorial for how to set up WiFi networking on the PiYou 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: The WiFi module may look slightly different than above, but all modules shipped are Pi-tested and contain the same chipset and have equivalent performance, the only difference is the plastic shell.

    Great WiFi dongle - really is just plug and play. Good signal strength for such a small adapter too.
    Good to know it will work with a Raspberry Pi before purchase too. (Posted on 14/06/2016)

    My first attempt at setting up my Raspberry Pi (model 2B) as a wireless access point was not not successful. It almost worked, but I couldn't see what I had done wrong compared to the instructions for the (different) adapter that I had that I found on the web.

    Looking around more I found this: https://learn.adafruit.com/setting-up-a-raspberry-pi-as-a-wifi-access-point?view=all
    set of instructions which seemed comprehensive and pointed out some of the things that could go wrong. I bought the Adafruit 814 (as used in the instructions) and followed the instructions through and it worked first time!

    Note also that this adapter seems to get enough power from the Pi's USB port - no need for a powered USB hub as well which, apparently is needed for some other adapters.
