    This is very handy 40-way male to female, 20 cm length of rainbow jumper wires. You will need it for making wire harnesses or jumpering between headers on PCB's. These premium jumper wires are a little over 7.5" (20cm) long and come in a 'strip' of 40 (4 pieces of each of ten colors). They have 0.1"(100 mil) 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. And with these features, this jumper wires is very suitable for Raspberry Pi 3 board. The GPIO on Raspberry Pi 3 is pre-soldered with 20x2 header pins.

    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"
