120Pcs 20cm 2.54mm Dupont Jumper Wire Cables (M-M, M-F, F-F)

These premium jumper wires are 200mm long and come in a ‘strip’ of 40 (4 pieces of each of ten rainbow colors). They have 0.1″ male / female header contacts on either end and fit cleanly next to each other on standard-pitch 0.1″ (2.54mm) header. The best part is they come in a 40-pin ribbon cable. You can always pull the ribbon wires off to make individual jumpers, or keep them together to make neatly organized wire harnesses.
