Adafruit Premium Female/Male Extension Jumper Wires 40 x 150mm

Premium Jumper Wires for Prototyping

These Adafruit extension jumper wires provide 40 flexible male-to-female connections measuring 150mm each. They suit engineers, students and hobbyists building temporary circuits on breadboards or linking headers on PCBs. The multi-coloured ribbon simplifies signal tracing during development and debugging.

Ribbon Format Fits Standard Headers

Each wire uses 28 AWG stranded conductors with 0.1 inch male and female contacts spaced at 2.54mm pitch. The strip keeps wires aligned for quick attachment to dual-row headers, yet individual cables can be peeled away when only a few connections are needed. This flexibility reduces clutter inside enclosures or on crowded benches.

Colour-Coded Ribbon Aids Organisation

Ten distinct colours appear four times each across the 40-wire ribbon, letting builders assign colours to power, ground, data or specific modules. The ribbon can remain intact for harnesses or be separated for point-to-point jumps. No software or additional accessories are included.
