Jumper Wire Kit (M-M, M-F, F-F)

The Jumper Wire Kit (M-M, M-F, F-F) is a must-have wiring assortment for every electronics workbench, school lab, maker kit and DIY project box. It includes 60 flexible multicolour Dupont-style jumper wires: 20 Male-to-Male, 20 Male-to-Female and 20 Female-to-Female cables. With all three common connector combinations available in one pack, you can quickly connect breadboards, Arduino boards, Raspberry Pi GPIO headers, ESP8266/ESP32 development boards, sensor modules, relay boards, displays and other 2.54mm pitch header-based electronics. Each wire is approximately 20cm long, giving enough reach for neat prototyping without excessive loose cable on a standard breadboard setup. The pre-crimped connector ends remove the need for soldering during circuit testing, making this kit especially useful for beginners, students, hobbyists and engineers who frequently change connections while debugging. The assorted colours also help with clear signal mapping—for example, red for VCC, black for GND and separate colours for data, trigger, PWM, I2C, SPI or analog signals. Male-to-Male wires are commonly used for breadboard-to-breadboard or Arduino-to-breadboard connections. Male-to-Female wires are useful for connecting development boards to modules with male header pins. Female-to-Female wires are ideal for module-to-module or GPIO header connections, including Raspberry Pi-style pin headers. These wires are intended for low-voltage, low-current electronics prototyping and should not be used for mains wiring or high-power loads. In the box: 60 jumper wires total—20 x M-M, 20 x M-F and 20 x F-F, approximately 20cm length, multicolour assorted. A simple, reliable and reusable jumper cable combo for fast electronic circuit building and testing.
