Pin headers, also known as pin sockets or pin connectors, are the most basic and widely used board-to-board/board-to-wire pluggable connectors in the field of electronic circuits. They are usually used in conjunction with matching female headers to achieve detachable electrical connections and signal/power transmission between printed circuit boards (PCBs) and between PCBs and peripherals/cables through plugging and unplugging. They are widely used in almost all electronic devices with PCBs.
