The RasPiO® Duino is a small plug-on board for Raspberry Pi. It has similar functionality to an Arduino Uno, but is fully programmable from the Raspberry Pi. Once programmed, it can be removed from the Pi and used on its own.
RasPiO® Duino is an easy, low-cost introduction to Arduino programming on the Raspberry Pi. The RasPiO® Duino kit contains everything you need to start Arduino programming (as long as you already have the Pi).
RasPiO Duino was designed using DesignSpark PCB
