These simple 15mm deep covers screw into the back VESA mounts on the SmartiPi Touch (with LEGO front or flat front) with the four included screws. They allow you to protect HAT boards and other electronic components that you might want for your project. They are made of ABS plastic and will have to be cut, drilled, or modified for your application. The case also helps protect the Ethernet and USB ports on the Pi B+,2 and 3.
Also available in large size.
