40 Premium Female to Female Jumper Wires with 10 colors.
These female-female jumper wires are handy for making wire harnesses or jumpering between headers on PCB's on the same or different boards. These premium jumper wires are 6" (150mm) long and come in a 'strip' of 40 (4 pieces of each of ten rainbow colors). They have 0.1" female header contacts 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.
