Pin Header 40 Pin Single Row

These 1×40 male pin headers come in a pack of 10 and are ideal for prototyping and modular builds; each strip uses a 2.54mm pitch for broad compatibility with Arduino, Raspberry Pi, shields, breadboards and custom PCBs. The single-row, 40-pin format makes it easy to add or extend connections, and strips can be cut to length to fit your board layout or shield pins without fuss. Designed for makers and engineers who value straightforward parts, these headers provide reliable, repeatable connections that simplify testing, stacking and permanent assemblies. Keep a few packs on hand to speed up iterations and reduce sourcing delays when moving projects from breadboard to finished hardware.
