OliExt is an extension you can plug on a A20 Olinuxino board from Olimex.

The main goal is to create a domotic system, I was first using Arduinos, then RaspBerry Pi and now I move to Olinuxino.

The story starts when I would like to automate shutters in my house, so I first designed modules to control shutters. I used Arduino as main controler. Then I moved to Raspberry Pi, and now I am working on a much more powerful board : Olinuxino.
