0.100″ (2.54 mm) Breakaway Male Header: 1×40-Pin, Straight, Black

These 0.1″/2.54mm-pitch header strips are commonly used as low-cost connectors. The standard spacing allows use with solderless breadboards, perforated prototyping PCBs, female headers, and our premium and pre-crimped jumper wires. The single-row header strips can easily be snapped into smaller strips to fit your application. The double- and triple-row strips can also be broken into smaller strips, but it takes a little more effort, and it is sometimes easier to use wire/diagonal cutters.
