In the world of electronics projects, we need headers, headers and more headers.
Each pack contains ten 40-pin break-away male headers, 0.1" (2.54mm) pitch. Breakaway headers are like the cello-tape of electronics. They're great for connecting things together, soldering to perf-boards, sockets for wires or break-away header, etc. We go through these guys real fast, and thought that given how handy they are, we'd offer them in a pack of ten!
These headers are even tin plated so they wont oxidize! You can cut these down to different sizes fairly easily, simply break apart, or use diagonal cutters to cut in between pins.
