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.\u003c\/p\u003e\n\u003ch4\u003eQ: Are these pin headers compatible with standard breadboards and Arduino shields?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\u003ch4\u003eQ: What is included in this 10-piece set?\u003c\/h4\u003e\n\u003cp\u003eA: You receive 10 pieces of 1×40 breakable pin header connector strips.
