40x1 Single In Line Male Pin Header

The 40×1 Single In Line Male Pin Header is a standard through-hole connector featuring a single row of 40 straight male pins with a 2.54 mm pitch. It is widely used for board-to-board connections, module interfacing, and prototyping. The header can be easily cut to the required length, making it highly flexible for custom PCB designs and development projects.
