Male-to-Male Breadboard Jumper Wire Set

Build and modify circuits quickly with this Male-to-Male Breadboard Jumper Wire Set, a practical 40-wire ribbon pack used in almost every electronics lab, Arduino kit and STEM learning setup. These are Dupont-style jumper cables with a male pin at each end, designed to plug directly into standard 2.54 mm breadboards, female header strips, Arduino female sockets, Raspberry Pi GPIO breakout boards and many sensor or relay modules. The wires are supplied as separable single-core jumper leads in assorted colours, so you can keep power, ground and signal lines visually organised while working on complex prototypes. Because both ends are male, they are especially useful for breadboard-to-breadboard links, breadboard-to-female-header modules, and quick test wiring on PCBs or development boards with standard female sockets. No soldering is required: simply insert the pin, test the circuit, move it when needed and reuse the same wire for the next project. This 20 cm length is a convenient balance for most bench-top builds: long enough to reach across a full-size breadboard or development board, but short enough to avoid excessive clutter. The wires are intended for low-voltage electronics, logic signals and small prototyping currents, not mains wiring or high-current loads. They are commonly used with Arduino Uno/Nano/Mega, ESP8266/ESP32 boards, Raspberry Pi GPIO experiments, breadboard power rails, LED circuits, sensors, buzzers, displays and motor-driver control inputs. In the box you get 40 male-to-male jumper wires, typically supplied as a connected ribbon that can be peeled into individual wires or kept grouped for multi-pin connections. Pin note: the exposed male pins follow the common 2.54 mm prototyping pitch and fit standard breadboard tie-points and female Dupont headers. A simple, low-cost essential for anyone building, testing or teaching electronics.
