0.100 (inches) (2.54 mm) Breakaway Male Header: 1×40-Pin, Straight, Double-Sided

These header strips have a 0.1″ (2.54 mm) pitch and are commonly used as low-cost connectors. The standard spacing allows use with solderless breadboards, prototyping PCBs, female headers, and our premium and pre-crimped jumper wires. The single-row header strips are available in a variety of lengths, and these are also easy to snap into smaller strips to fit specific application requirements. The double- and triple-row strips, which are only available in 40-pin lengths, can also be broken into smaller strips, but it takes a little more effort, and it is sometimes easier to use wire/diagonal cutters.

This connector is a single-row, 40-pin, straight male header strip that can be cut or broken into smaller strips. 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 adapter, and both sides are compatible with wire wrap.
