Frequently asked questions
Is this header compatible with breadboards and Arduino boards?
Yes. The 2.54 mm (0.1 in) pitch matches standard breadboards, Arduino headers and most maker modules.
How do I cut the header to length?
Count the number of positions you need, then cut through the plastic housing between positions with wire cutters. Remove any burrs with a file before inserting it into your board.
