MyPiFi LED Board
If you are just starting to play with the GPIO pins on the Raspberry Pi then this little board is perfect to get your started.
Featuring 3 LEDs and a switch that can be programmed in your language of choice to provide feedback on any events from receiving an email, tell you when the internet connection has gone or even when it is home time!
1 Tactile switch
1 Extended GPIO header
This comes in kit form, so some soldering assembly is required.
