Using this case is a breeze. First, place your 7 - inch Raspberry Pi touch screen and the Raspberry Pi 3 board inside the case. Use the four provided screw fixings to attach the touch screen properly. The cut - outs are there for all the connections, so you can easily plug in your cables. If you want to mount it on the wall, just use the wall - mount features. When you need to access the internal connectors, simply open the easy - clip rear cover. As for maintenance, keep it clean by using a soft, dry cloth. Avoid using harsh chemicals or abrasive materials. Also, make sure to keep it in a cool and dry place to prevent any damage to the case and the devices inside.
