Review: Headers for your breakout boards - Not sure what to say, they're headers. They do what they do, and break apart easily. Fast delivery.
Review: Good supply of all the most common headers - 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.

## Features

- 【Size】40 pin of each male or female header connectors, with 2.54 mm/ 0.1 inch pin pitch. Single-row, straight connector.
- 【Cuttable】You can cut them, please score them with some cutting tool, and snap them off, they can be cut to arbitrary length if needed.
- 【Function】Acts as a bridge between the blocked or isolated circuits in the circuit, and assumes the task of current or signal transmission.
- 【Application】 Best choice for a good connector to connect PCB boards and integrated circuits. Very suitable for PCB circuit boards in electronics, electrical appliances, meters and so on, help you to solve the problem.
- 【Package Includes】Total 20pcs header connectors, includes 10pcs male headers and 10pcs female headers, enough to meet your needs without leaving idle materials.

## Questions & Answers

**Q: what is the diameter of the pins?**
A: standard pin size .1 works flawless with the pin headers on ardunio

**Q: Can these be broken into different length sets?**
A: They can be broken to length, but it usually requires on pin to be sacrificed because it doesn't break cleanly. I recommend using a cutting tool rather than breaking by hand though.

**Q: Are pins on female suitable for thru-hole mounting on a pcb? what are the pin dimensions?**
A: I believe the female pins will work fine in printed circuit boards that have plated through holes, with proper soldering techniques.  These connectors appear to be the standard cut to length parts that you can adjust the number of pins by using an exacto knife to separated them.  Doing this however sacrifices one pin position.

**Q: What is the current rating on these? Will these be okay for 2 Amps?**
A: I doubt they can handle more than a breadboard - 500 mA.

### ⭐⭐⭐⭐⭐ Headers for your breakout boards

### ⭐⭐⭐⭐⭐ Using headers can accommodate future changes.
*by R***W on June 30, 2025*

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.
