Male-to-Female Jumper Wires, 40-Pin, 30cm, Multicolor

A 40-piece set of male-to-female jumper wires covers one of the most frequently needed connection types in breadboard prototyping and microcontroller wiring - connecting a bare pin header (like those on a sensor module or Arduino) to a breadboard's own female socket rows, or bridging between two boards where one side has pins and the other needs a socket connection.

Each wire measures 30cm, long enough to comfortably route between a breadboard and a microcontroller board sitting a reasonable distance apart on a workbench, or to reach around other components in a more cluttered build without needing to reposition everything into a tight cluster. The multicolor assortment makes it considerably easier to visually trace which wire goes where in a project with more than a few connections, rather than hunting through a tangle of identical black wires.

Compatibility with the standard 2.54mm pin header spacing used across the vast majority of breadboards, Arduino-family boards, and sensor module headers means these wires work as a default choice for prototyping wiring without needing to check pin spacing compatibility first. The male end pushes directly into a breadboard's female socket rows or a female header, while the female end slides directly onto a bare male pin header.

Hobbyists, students, and makers doing breadboard prototyping or general microcontroller project wiring who need a reliable, color-coded way to connect pin headers to breadboard sockets will find this 40-piece male-to-female jumper wire set a practical, frequently-reached-for addition to a basic electronics toolkit.
