This set includes 10 long, stackable female headers, each with 6 pins and a pitch of 2.54mm. What sets these headers apart is that the pins are gold plated, providing excellent conductivity and durability. These headers are perfect for building Arduino shields but are also versatile enough for other electronic projects. The stackable design feature allows for multiple shields or components to be stacked on top of each other, saving space and increasing functionality. They are easy to install and come in a set of 10 pieces.
