These premium female-to-male extension jumper wires are ideal for making wire harnesses or extending connections between headers on PCBs. Each strip contains 20 wires (2 of each rainbow colour) in a convenient ribbon cable format that can be kept together for organised harnesses or separated into individual jumpers.
Key Features
- Female-to-Male – 0.1" (2.54mm) female header on one end, male header on the other
- 300mm (12") Length – Generous reach for most prototyping setups
- 20-Pin Ribbon Cable – Stays organised; peel off individual wires as needed
- 10 Rainbow Colours – 2 wires per colour for easy circuit identification
- Standard 0.1" Pitch – Fits cleanly on standard 2.54mm header pins
Package Contents
- 1× Strip of 20 female/male jumper wires (300mm)
Tip: When plugging wires in a row, orient the side with the silver latch facing outward — that side is slightly wider than 0.1".
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.
