Female headers are like the duct tape of electronics. They are 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 20-pin 0.1" pitch female headers in your choice of colour. Also available in a rainbow pack with one of each colour.
You can cut these down to different sizes fairly easily with diagonal cutters to cut in between pins
