2.54mm Single Row Male Pin Header — 1×40 Breakable Strip (5pcs)
The standard 2.54mm (0.1") pitch single row male pin header is the most widely used connector in electronics prototyping. This listing provides 5 strips of 1×40 pins, breakable to any length from 1 to 40 pins. Gold-plated contacts ensure reliable conductivity and corrosion resistance.

- JTAG/SWD Debug Headers — 2×5 or 1×4 debug port headers
FAQ
Q: How do I break the strip to a specific length?
A: Score the insulator between the desired pins with a knife or snap it over a hard edge. The strip breaks cleanly at any pin position. Note: the pin at the break point may be lost.
Q: Are these compatible with DuPont female jumper wires?
A: Yes. Standard 2.54mm DuPont female connectors (as used on Arduino jumper wire sets) fit these male headers perfectly.
Q: What is the difference between long and short pin headers?
A: Long pin headers (11.5mm above insulator) are used for stackable Arduino shields. Short pin headers (6mm) are standard for direct PCB mounting. Check the variant options for the length you need.
