## Description

Handy for making wire harnesses or jumpering between headers on PCB's. These premium jumper wires are 12" (300mm) long and come in a 'strip' of 40 (4 pieces of each of ten rainbow colors). They have 0.1" male header contacts on either end and fit cleanly next to each other on standard-pitch 0.1" (2.54mm) header. The best part is they come in a 40-pin ribbon cable. You can always pull the ribbon wires off to make individual jumpers, or keep them together to make neatly organized wire harnesses.

Adafruit have these in three handy lengths: [3"/75mm](https://core-electronics.com.au/premium-male-male-jumper-wires-40-x-3-75mm.html), [6"/160mm](https://core-electronics.com.au/premium-male-male-jumper-wires-40-x-6-150mm.html) and [12"/300mm](https://core-electronics.com.au/premium-male-male-jumper-wires-40-x-12-300mm.html). If you want the [female/female type, Adafruit have those too!](https://core-electronics.com.au/premium-female-female-jumper-wires-40-x-6.html)

**Note:** The length of the jumper wires is sometimes a bit longer than what is listed.

For best results, when plugging these in a line, have the sides with the 'silver latch bit' sticking out since that side is a tiny bit wider than 0.1"

## Technical Details

Each wire is 28 AWG (7 strands @ 36 AWG)
