UDOO BRICKS are modules you can use to augment your UDOO BOARDS and make them more versatile. Attach them into I2C Bricks snap-in connector with the related cable. UDOO BRICKS work along a cascade configuration, so you can attach them all together without wasting space in a truly intuitive way. Thanks to such configuration you can use cables up to 3,5 m long to connect UDOO BRICKS one another.
