## Description

These jumper wires come with a twist! Instead of going from 0.1"/2.54mm pitch headers to breadboard or something like that, these are **2.54mm to 2.0mm**! Handy for making wire harnesses or jumpering to annoying 2mm-pitch connectors, these premium female-female jumper wires are around 6.5" (170mm) long and come in a 'strip' of 40.

Each pair of wires has 2 pieces of 2.54mm (.1") socket on one end and a single 2x2.00mm (.08") socket on the other on the other end (1x2mm aren't available). This allows you to connect products with 2.00mm header spacing like the [XBees](https://core-electronics.com.au/#) to a breadboard! Just put extra-long male headers in the breadboard and connect!

These come in a ribbon strip but you can always pull the ribbon wires off to make individual jumper wires OR keep them together to make neatly organized wire harnesses.

We suggest [picking up some extra-long break-away header pins as well](https://core-electronics.com.au/extra-long-break-away-0-1-16-pin-strip-male-header-5-pieces.html), you can stick those into the sockets to turn the cables into 2mm socket to 2.54mm male!

**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" or .08".

## Technical Details

- Length: 170mm
- Each wire is 28 AWG
