A ribbon of 40 premium female-to-male jumper wires, 150mm (6") long, in 10 rainbow colours (4 wires per colour). Each wire has a 0.1" (2.54mm) female header socket on one end and a 0.1" male pin on the other, fitting standard-pitch headers. The ribbon can be kept together for organised wire harnesses or peeled apart into individual jumpers.

Key Features

  • 40 Wires – 10 colours, 4 wires per colour in a peelable ribbon
  • Female-to-Male – Extension/jumper wires for header-to-header connections
  • 150mm (6") Length
  • 0.1" (2.54mm) Pitch – Compatible with standard breadboards and PCB headers

Ideal For

  • Extending GPIO connections on Raspberry Pi, Arduino, and microcontrollers
  • Breadboard prototyping
  • Creating organised wire harnesses
  • Jumpering between PCB headers

Package Contents

  • 40× Female-to-male jumper wires (150mm, ribbon)
Tip: When plugging wires side by side on a header, orient them with the silver latch facing outward, as that side is slightly wider than 0.1".

Jargon buster

Plain-language definitions for the technical terms used above.

GPIO
General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
Headers
Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.
PCB
A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
