Breakaway header is like the duct tape of electronics. Its great for connecting things together, soldering to perf-boards, fits into any breadboard, 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!
Each pack contains 10 x single row, right angle male 1x36-pin long headers, 0.1" pitch, that can be stacked next to each other on a 0.1" grid and broken apart easily with pliers or diagonal cutters. They're even gold plated so they wont oxidize!
2.54mm (0.1") 40-pin break away single row male header. It can be cut to size with a pair of wire-cutters. You can use them for many projects; for example with the Arduino shields.
• Contact spacing: 2.54mm (0.1") • Number of positions: 40 • Number of rows: 1 • Gender: male • Termination type: 90 degree • Mounting style: through hole
