Handy for making wire harnesses or jumping between headers on PCB’s or Breadboard.
These premium jumper wires are a little over 20cm long and come in a ‘strip’ of 40.
They have 0.1″ sockets on either end and fit cleanly next to each other on standard-pitch 0.1″ (2.54mm) header.
You can always pull the ribbon wires off to make individual jumpers, or keep them together to make neatly organized wire harnesses.
