A header connector is a type of electrical connector used to connect wires or cables to a circuit board. It typically consists of a series of pins or sockets arranged in a row, allowing for easy attachment and detachment of components. These connectors are commonly found in various electronic devices, including computers and smartphones, facilitating communication between different parts of the system. Header connectors come in various sizes and configurations, such as 2.54mm or 1.27mm pitch, depending on the application. They are often used in conjunction with jumper wires or ribbon cables to create flexible connections. Their design allows for quick assembly and disassembly, making them ideal for prototyping and testing in electronics.
