40-Piece Dupont Jumper Wire Set (M-M, M-F, F-F)

Every breadboard-based project eventually needs jumper wires, and the three connector combinations covered here - male-male, male-female, and female-female - handle essentially every wiring scenario a hobbyist project runs into, whether connecting two breadboard rows, a breadboard to a header pin, or two header pins directly. Standard 2.54mm pin spacing means they fit the pin headers found on virtually every development board, sensor module, and breadboard on the market without needing to check compatibility first.

At 20cm each, the wires reach comfortably across a typical breadboard layout or between a board and a nearby module without needing to stretch tightly or double up wires for extra length. Multicolor wire coding, while not functionally necessary, makes tracing a specific connection back through a busy breadboard layout considerably faster than an all-black wire set would.

Common uses are prototyping any Arduino, ESP32, or Raspberry Pi project on a breadboard, connecting sensor and driver modules that use header pins rather than screw terminals, and general electronics workbench wiring where a reliable, reusable jumper set is a basic requirement.
