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 8" (200mm) 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 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, you can stick those into the sockets to turn the cables into 2mm socket to 2.54mm male!
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".
