Female header is like the duct tape of electronics. It's great for connecting things together, soldering to perf-boards, sockets for wires or break-away header, etc. We go through these real fast, and thought that given how handy they are, we'd offer them in a pack of five!
Each pack contains five candy-colored 20-pin 0.1" pitch female headers. These are a little extra special in that the plastic holding the pins together is made of colored plastic instead of classic black.
You get 1 of each color: red, yellow, white, green, and blue. This pack does not include black headers.
You can cut these down to different sizes fairly easily with diagonal cutters to cut in between pins.
