20PCS Pin Header, 2.54mm 40Pin Male and Female Header Pins Breakaway PCB Board Connector Single Row Pin Headers Strip for Arduino Shield

Great product. Exactly as advertised

Not sure what to say, they're headers. They do what they do, and break apart easily. Fast delivery.

Perfect

Used these to interface to an Arduino. Changes can be made in the future if needed to acommodate wiring changes with new header without having to modify the Arduino. I keep some empty pins on the header to secure extra grip force when header is inserted into Arduino sockets.

I used these to breakout a stepper motor driver. I used both male for motor pins and female for logic pins... The males worked flawlessly! The females were a pain. The design needs to be adjusted so there is a score between pins. Similar to the males that will aid in snapping or cutting. When I split them I used sharp nippers. I had to sacrifice the pin after the cut. Then once cut I used an xacto knife to clean the edges... Edges are not easy to get straight either... Otherwise these pins function as designed!

It's a good assortment of headers, pins and sockets. This is for boards, not so much for cable-ends, though one could improvise a cable end connector with these. The only trouble with these is that for the female socket strips, cutting it down to size requires crushing and sanding away one of the sockets, but that's no fault of the product, it's just the way it works, and all similar products are the same way. They are cheap enough that I don't care, but I've seen people complain about it. I've used these in several projects and fixes, and they have performed wonderfully.

These work well with my various Arduino processors.

This kit of male and female PCB board pins have been great. I have used these pins in many different configurations and they always have worked well for me.

The header worked well in my electronic project. Fit together is adequate.
