Digi international offers a verity of wireless modules in a standard
form-factor. Modules range from low power Zigbee modules, capable of
mesh or point-to-point connections, to high-powered modules reaching up
to 15 miles!
Another important XBee offer is the WiFi option. Some gadgeteer mainboards may not have support for the WiFi RS21 Module
GHI offers. These mainboards can use the Xbee module plus XBee-WiFi as
an alternative. The difference is that GHI's WiFi Module enables FEZ
Spider with a real WiFi connection that uses the standard .NET socket
class. On the other hand, XBee WiFi is simply a WiFi to serial bridge
with many limitations but still good enough for many applications.
These modules are available from hundreds of stores around the world, just search the web for XBee.
Requires Socket type U.
.NET Gadgeteer compatible cable is included.
