Miniature WiFi (802.11b/g/n) Module: For
Raspberry Pi and more
PRODUCT ID: 814
DESCRIPTION
-
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. We 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! We 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 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. For installation projects or large-scale distribution, we 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. We 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
