Frequently Asked Questions
Q: Can these pin headers be cut to a custom length?
A: Yes! These are breakable pin header strips, meaning you can snap them at any point along the 40-pin row to achieve the exact pin count your PCB or project requires. No special tools are needed — just apply gentle pressure at the desired break point.
Q: Are these pin headers compatible with standard breadboards and Arduino shields?
A: Absolutely. The 2.54mm (0.1-inch) pitch is the industry-standard spacing used by Arduino, Raspberry Pi, breadboards, and the vast majority of DIY development boards and PCB shields, making these headers universally compatible.
Q: What is included in this 10-piece set?
A: You receive 10 pieces of 1×40 breakable pin header connector strips. The set includes both male and female connector strips, giving you everything needed for a complete plug-and-socket connection in your electronics project.
