These housings work with our wires with pre-crimped terminals and our crimp pins to let you quickly make custom cables that mate with various 0.1"-spaced connectors, including male and female headers and solderless breadboards. Just pick the housing for the correct number of pins, pick the colors and genders for your wires, and snap them into the housings (note: it’s not easy to get the wires back out, so plan carefully!).
