Using this Pibow touchscreen frame is a breeze. First, take out the frame and the supplied bolt pack. You can directly screw the three layers of the frame onto the back of your 7 - inch Raspberry Pi touchscreen without needing any tools. After that, adjust the two legs to set your screen at an ideal viewing angle for comfortable use. Remember, this frame is just a mount, so you'll need to provide your own screen and Raspberry Pi. When it comes to maintenance, simply use a soft, dry cloth to wipe the frame clean. Avoid using harsh chemicals as they may damage the frame's finish. Keep it in a dry place to prevent any rusting of the bolts. Enjoy using your new frame in one of the six beautiful colors it comes in!
