This connector is a single-row, 40-pin, straight male header strip that can be cut or broken into smaller strips. This strip has a blue plastic base; other colors are available.
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.
We carry the following 0.1″-pitch breakaway male headers:
Pololu - 0.100" (2.54 mm) Breakaway Male Header: 1x40-Pin, Straight
Pololu - Dimension diagram of 0.100" (2.54 mm) Breakaway Male Header: 1x40-Pin, Straight
1×40-pin, straight, double-sided (Both sides of the strip are long, allowing for unique connections that cannot be made with standard male header strips. For example, this header can be used as a female-to-male adaptor, and both sides are compatible with wire wrap.)
