Ubiquiti Ministation AP Board

I have been interested in the Ubiquiti Ministation Wifi AP for a while now and recently purchased one. It is marketed as “The World’s Smallest 802.11 AP Development Platform with a full Linux SDK available”. I have had a chance to play with it for a few weeks now and must say that the hardware and the bundled router operating system called “Air OS” is excellent. The web based user interface is easy to use and works well. All of the settings a normal user would want are available and quick to setup. There is even a dialog and special mode that helps with antenna pointing that has onscreen colored signal strength bars and configurable LEDs on the AP board that give you an idea on the signal strength of the link at a glance.

The second one can be used easily for connecting GPS units, microcontrollers, weather stations or any other serial device.
