The 1 Line 40 Pins Female Header (also called 1×40 female header strip) is a standard PCB connector widely used in Arduino, Raspberry Pi, ESP32, STM32, and embedded electronics projects. Each strip contains 40 female pin sockets arranged in a single line, with 0.1 inch (2.54mm) pitch, making it compatible with most development boards, jumper wires, and pin headers. These headers can be easily cut into smaller sections such as 1×2, 1×6, 1×8, or 1×10 to suit specific requirements. Built from copper alloy contacts with durable plastic housing, they ensure secure mechanical connection and reliable electrical conductivity. Ideal for IoT, robotics, sensors, power modules, and custom PCB assemblies, they simplify prototyping and permanent soldered builds.
