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

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.

Value for money

Low cost and work well.

Arrived quickly and as described. Standard 2.54mm spacing pins.

VERY fast delivery. Exactly as described.

Decent header pins, large enough quantity that I don’t see myself buying more anytime soon. Soldered with them normally. Nothing remarkable.

-I agree with the other reviewer re: solderability. I could barely get my aggressively fluxed solder to stick until I cleaned the solder end thoroughly first. I used 99% rubbing alcohol, wiped on and wiped dry, twice just to make sure. Solder problem solved. -They dont break apart as precisely as some of the others by hand, using needle nose pliers helps a lot.

Good

They are normal header pins. No issues.

Pins plugged into my arduino board. Exactly the right size.
