Description: The pin header is a row of pins used to establish electrical connections between a circuit board and other components or devices. These pins are essential in electronic circuit design, as they allow for the interconnection of different modules and the expansion of functionalities. Typically, pin headers are arranged in standard configurations, such as 2×5, 2×10, or 1×40, making them easy to use in prototypes and electronics projects. The pins can be male or female, determining how they connect to other components. The versatility of pin headers makes them a popular choice in various development platforms, where they are used to connect sensors, actuators, and other modules. Additionally, their design allows for easy insertion and removal, which is crucial in prototyping environments where frequent changes to the circuit are made. In summary, the pin header is a key component in modern electronics, providing a simple and efficient interface for connecting various elements in an electronic system.
