MCIGICM 10pcs Male Header Pin, 40 Pin Header Strip (2.54 mm) for Arduino Connector

What can i say , they are header pins. However with that said they are of good quality and quantity for the price and I was pleased with the simple yet effective packaging .. Would buy from again.

I needed some headers on a raspberry pi pico to use with a breadboard. Worked perfect, good price w/prompt delivery! Use for

Good Product

This has the same spacing as standard Arduino headers. The long side is right for going into the raised sockets on the Arduino (or a shield with stacking headers). The top pin comes out the top of the next board by 2 mm or a little less. Perfect for when you want a soldered connection but will not be adding anything to the top side. I'm working on a project where I have to stack and unstack custom shields multiple times. These pins stand up to that nicely. Much better than stacking headers, which always seem to use flimsy legs that bend too easily. Of course you should still make an effort to move these pins in and out vertically, but I'm not perfect and so far my slips have caused no damage.

They do the job but the plastic can slide off the pins easily. The hold very well in solder-less breadboards.
