Jumper Wire Kit (120 Pieces)

This kit covers all three jumper wire configurations a breadboard project typically needs: male-to-male for board-to-board connections, male-to-female for connecting a breadboard to header pins on a module, and female-to-female for linking two sets of pins directly. Having all three types on hand avoids the common mid-project problem of having the wrong connector type for a new component.

Each wire uses stranded copper conductor inside a color-coded PVC jacket, and the pin ends are tin-plated to resist oxidation, which keeps the connection reliable even after a wire has been stored for months between projects. The assorted lengths in the kit range from short jumps between adjacent breadboard rows to longer runs across a full board.

The pins themselves are sized to the standard 0.1-inch header pitch used on breadboards, Arduino-style boards, and most hobbyist modules, so they seat firmly without excess play. The full set is small enough to store in the included compartment case rather than loose in a parts drawer.
