A 40-pin ribbon of female-to-male (F/M) jumper wires, 30cm long, in ten rainbow colours. The wires fit standard 0.1″ (2.54mm) pitch headers and can be kept as a ribbon for neat harnesses or separated into individual jumpers.

  • Female-to-Male (F/M) – 0.1″ female header on one end, male pin on the other
  • 40-Pin Ribbon – Separable into individual wires as needed
  • 30cm Length – Extra reach for larger projects and enclosures
  • Rainbow Colour-Coded – 10 colours for easy identification
  • 2.54mm Pitch Compatible – Fits standard header pins and breadboards

Ideal For

  • Extending header pins to a breadboard
  • Connecting sensors and modules to development boards
  • Raspberry Pi and Arduino GPIO connections

Package Contents

  • 1× 40-pin F/M Jumper Wire Ribbon (30cm)

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.
