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

VERY fast delivery. Exactly as described.

Quality and quantity at a great price! These pins worked perfectly on an iRangeX Multi Module board to enable firmware updates.

Been using these for a while and theyre solid, melting point on the plastic is a bit lower than my previous set, but doesnt impact projects unless I overdo the temp on my iron

All the headers came broken, very disappointing!

I needed to attach some pins to my Teensy 4.1 to connect a USB port to it. These worked perfectly and snapped cleanly where I needed it to. This was a great value and I plan on using some more when I build my first keyboard!

Got the wrong ones and now I have these. They’re exactly what they say they are I just needed smaller ones

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. Im 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 Im not perfect and so far my slips have caused no damage.

Very good.

Good reliable headers

What can I say? They are exactly what they claim to be.
