Using this short 2x20 female GPIO header is a breeze. First, identify your Raspberry Pi model (A+, B+, or Pi 2). Then, simply plug the Raspberry Pi HAT onto the header on your Pi. It's that easy! When handling, be gentle to avoid bending the pins. As for maintenance, keep it clean and dry. If you notice any dust, you can use a soft brush to remove it. And always make sure it's properly seated to ensure a good connection.
