The shield board dimensions are 2.02" × 2.56" (within the profile of the standard Arduinos). When the shield—with a socketed Wixel—is plugged into an Arduino Uno, the entire assembly is 1.3" tall.
With the socketed Wixel but without the extended 1×8 and 1×6 shield headers, the shield itself is 0.8" tall. Since the height of the Wixel and its socket is taller than the typical available clearance between shields, we recommend using the Wixel shield as your Arduino’s top shield.
The mounting holes are 1.7" apart and 0.125" in diameter, suitable for #4 screws.
