At least for prototyping, is there a semi-permanent way to attach wires to the Nano posts?

Arduino nano

And yes, usually the Nano is hanging in free space by its wires (yes I know, quick and dirty, should be using something cleaner, even for prototypes). So I'm hoping for the best of both worlds, sturdy "enough" to stay attached, yet possible to remove and switch around. Having no luck finding such advice on the internet, perhaps searching for the wrong terms.

EDIT: I neglected one important point, each wire is attached individually just like the SparkFun wires with the female header as mentioned in @TheDoctor's answer below.

  • Not sure exactly what you're looking for. Dupont connector, maybe? – Luke Feb 13 '14 at 16:16

    What about a breadboard? They're useful so the wires are a little more secure. – Steven10172 Feb 15 '14 at 5:09
  • Don't forget about soldering. It is a time proven semipermanent to permanent way of attaching wires. – Wirewrap Jul 20 '15 at 10:31
  • You are trying to do something in a harder and less effective manner than you could be. Yes, there are ways of doing what you want. No, it is almost certain that not using a breadboard makes sense. There may be constraints which make various solutions unsuitable but, if so, you should include them in your question. – Russell McMahon Jul 20 '15 at 13:28

There are jumper wires that have a female header on one end and a male header on the other. Example: https://www.sparkfun.com/products/9140

jumper wires

You could also attatch several wired to a strip of breakaway female headers, such as https://www.sparkfun.com/products/115

    The row of female headers, shown in the second link, is the way to go, since the individual wires have a tendency to pop out every now and then, whereas the entire row is much more secure. – Chris O Feb 13 '14 at 18:21

A wire wrap tool can work well for this - the wrappings tend to be fairly secure if done right, though the wire itself can break if stressed.


The entire premise behind Gravitech's design of the Arduino Nano was for it to be plugged into a breadboard. If done so, then none of the pins are left dangling. From Arduino's webpage for the Nano:

The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x) or ATmega168 (Arduino Nano 2.x). It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one. The Nano was designed and is being produced by Gravitech.

From Gravitech's webpage for the Nano:

Arduino Nano is a surface mount breadboard embedded version with integrated USB. It is a smallest, complete, and breadboard friendly.


Nano’s got the breadboard-ability of the Boarduino and the Mini+USB with smaller footprint than either, so users have more breadboard space.

If you have a Nano in such a dangling state, then you are using the wrong sort of Arduino board for the wrong purpose.

Obviously a Nano will work just fine when loose on a surface, i.e. not plugged into a breadboard, but that is not what it was intended for, and maybe you should employ an UNO in its place.

However, if you have to use your Nano without a breadboard, then in addition to the wire wrapping, wires with female DuPont connectors, or female header strips, you could just solder wires to the holes in the nano board, if you do not already have header pins already soldered in to them.


Here's what I use, repeatedly, successfully. It fits the Nano headers, and gives you screw terminals for proto work.
