This is a 2.54mm 1x40 Pin Female Single Row Header Strip that can be mounted on PCB. Female headers are the most basic and are usually included with any board that uses them. If you wish to build your idea into a breadboard - solderless or permanent - use male headers. If you wish to stack your boards together, you can use them in combination with male headers.
