Review on 🔌 MCIGICM 10pcs Male Header Pin, 40 Pin Header Strip (2.54 mm) - Arduino Connector by Jasmine Reed

It's the same spacing as standard Arduino connectors. The long side is suitable for connecting to the raised headers on the Arduino (or shield with stacked headers). The top pin protrudes 2mm or slightly less from the top of the next board. Ideal when you need a solder joint but don't want to add anything to the top. I'm working on a project that will require me to fold and unfold custom shields multiple times. These pens hold up well. Much better than stackable headers that always use weak legs that bend too easily. Of course, it still takes effort to move those pens vertically, but I'm not perfect and my slip-ups haven't hurt so far.
