Protect your Raspberry Pi with the Raspberry Pi Case 3 B 2 B. Click the Pi on the bottom of the case. There is a recess in the case for each connection on the PCB. The engraved names clearly show you where every cable needs to go, without opening the case. Thanks to the rubber feet you can also place the case on your shiny TV furniture without damaging it. This is how you use your Raspberry Pi as a media player.
