The PiStorms module transforms your LEGO robot into a Raspberry Pi robot. The module is designed as an interface between the Raspberry Pi board and any of the LEGO Mindstorms NXT or EV3 motors and sensors. It is compatible with Raspberry Pi A+, B+ and Pi 2. On top of the module is attached a 2.4-inch color touch screen display. You have to connect your Pi board and interact with the display.
