Using this Pimoroni Raspberry Pi 7 - inch touchscreen display case is a breeze. First, place your Pi Foundation PiTFT - 7' touchscreen display into the case. Since there are no tools required for assembly, you can simply fit the parts together. The three - layer design provides support and protection to the back of the display, so make sure it's properly seated. Adjust the two sturdy legs to get the ideal viewing angle for your touchscreen. Remember, this case is just a display mount, so you'll need to have your own screen and Raspberry Pi. Also, ensure that your Raspberry Pi has a DSI port as the case is compatible only with Pi models having this port. For maintenance, just use a soft, dry cloth to wipe the case clean. Avoid using harsh chemicals that might damage the Noir finish.
