40x1 Single In Line Female Pin Header

The 40×1 Single In Line Female Pin Header is a single-row through-hole socket header designed to provide reliable and reusable connections between PCBs and male pin headers. With a standard 2.54 mm pitch, it is widely compatible with Arduino, Raspberry Pi, ESP, and other development boards. The female socket design allows easy insertion and removal of mating pins, making it ideal for prototyping, testing, and modular circuit designs.
