Handy for making wire harnesses or jumpering between headers on PCB's. These premium jumper wires are a little over 200mm long and come in a 'strip' of 20 (2 pieces of each of ten colors). They have 2.54mm sockets on either end and fit cleanly next to each other on standard-pitch 2.54mm header. We recentlty updated these so they are in a 'ribbon strip' instead of individual wires. You can always pull the ribbon wires off to make individual jumpers, 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 female-male or male-female jumpers!
These jumper wires can be used for pretty much everything! They work great with breadboards, Arduinos, and really any 0.1" pitch prototyping board.
The length of the jumper wires is sometimes a bit longer than what is listed.
