Using these pogo pins is easy. First, find a standard perf board hole that fits the pins snugly. Then, just solder them onto the board like you would with normal wire. These pins are great for programming, so you can use them in your programming jigs. Remember, don't force the pins into holes that are too small as it might damage the pins. When not in use, keep them in a dry place to prevent rust. And if you need to check the size details, you can refer to the dimensional drawing.
