Can the GridEYE sensor be connected to the EV3 Mindstorms? Yes, it can and it is actually not that difficult. This post shows the progress that has been made on the hardware integration.
The first prototype was a breadboard project were we connected the Panasonic GridEye developers board to the EV3.
To make things more fance, a PCB was designed. This is what it looks like. The size will be 46 x 32 mm.
These are the SMD (surface mount device) components to assemble a number of these boards.
This is the sensor board equiped with all the component and the GridEYE sensor.
