A pack of 20 premium male-to-male jumper wires in a convenient ribbon cable format. Each wire is 75 mm (3") long with 0.1" (2.54 mm) male header contacts on both ends, fitting cleanly onto standard-pitch headers.

The 20-pin ribbon includes two wires in each of ten rainbow colours for easy identification. Pull individual wires off as needed, or keep them together to create neat, organised wire harnesses.

Key Features

  • Male-to-Male Contacts – 0.1" (2.54 mm) pitch header pins on both ends
  • 75 mm Length – Ideal for short jumps between headers on a breadboard or PCB
  • 20-Pin Ribbon Cable – Separable into individual wires or kept as a harness
  • Rainbow Colour Coded – 10 colours, 2 wires each, for easy circuit identification
Tip: When plugging these in a line, orient them with the silver latch side facing out, as that side is slightly wider than 0.1".

Package Contents

  • 20× Premium Male/Male Jumper Wires (75 mm, ribbon cable format)

Jargon buster

Plain-language definitions for the technical terms used above.

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.
male-to-male
A male-to-male cable has plug-style connectors on both ends rather than a socket on one end. This matters when choosing a cable because it must match the female sockets on the modules or boards you want to connect.
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.
