Product name: GPIO Rainbow Cable (Female/Male) 200mm - 40 ways
Details:
These premium jumper wires are 200mm long and come in a 'strip' of 40 (4 pieces of each of ten colors). They have 0.1" female and male sockets on each 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.
