RasPiO Breadboard Pi Bridge lets you... build and control a circuit with very few additional wires attach a breadboard to your Pi neatly, robustly and reversibly make prototype circuits quickly and easily make far fewer wiring errors, saving debugging time and potential damage ...so it's ideal for experimenting with Pi-controlled circuits, prototyping and learning. The RasPiO Breadboard Pi Bridge PCB connects all available Raspberry Pi GPIO ports to a half-size breadboard, with an elegant Perspex platform and cover holding it all neatly and robustly together. The Pi GPIO ports connect to the breadboard in numerical order (2-27), which means no pin counting and fewer wiring errors - just add your components to the breadboard and start controlling it with the Pi.
