Using this GPIO female header is easy. First, connect your own PCB to the Raspberry Pi B+. It works well with Raspberry Pi Model A+, Pi 2, and Pi 3 too. Since the pins are 3mm long, you don't need to cut them. This makes it super convenient for basic Pi HAT design. When handling the header, be gentle to avoid bending the pins. As for maintenance, keep it in a dry place. If it gets dirty, you can use a soft brush to clean it. Remember, each order comes with one header, so make sure you have enough if you need multiple ones for your project.
