Sorry if this has been posted before...

I'm looking for some prefab header innerconnects for my home Arduino oriented projects.  Stuff to connect the output pins to other devices that are in the 0.1" (2.54mm) pin configuration.

I found this nice looking 1 on Amazon but think it is a bit overpriced:
http://www.amazon.com/StarTech-com-18-Inch-Internal-Motherboard-USBINT5PINMF/dp/B005G306UK/ref=sr_1_1?s=electronics&ie=UTF8&qid=1343074436&sr=1-1&keywords=header+cables

But that is about the "quality" I am looking for.  If you can recommend a good set of cable + connectors + crimpers that would be nice too but I think a modest assortment of prefab cables would be good.  Crimpers tend to be rather pricey....

My "immediate" need is to connect my Arduino NANO that is on a breadboard to this 4 channel relay module:

Looks like I'll need a 6-pin cable for that one.  Any ideas on where I can get an assortment of prefab cables?

Again, thanks for your help and sorry if this is something that keeps getting asked.  It is just very difficult to identify even the language to use for these things.  (I know, I'm full of excuses...)

Maybe the servo extension or other RC interconnect leads that are sold on Ebay

I agree that the crimping tool is expensive and you would have to be making a lot leads to justify the cost.

Here's another option. These ribbon cables can be split to suit the number of cores you need. Many sources other than eBay for these.

Thanks!  I think that rainbow color 40 way cable is what I'm looking for.

Do those end pieces just snap into the connector housing?  Do I need another crimp tool for those connectors?

Question #1: Yes, each pin or receptacle has a retaining clip with a tab that fits into slots in the plastic casing.  If you are very dextrous and have needle nosed-pliers and jeweler sized screwdrivers you can even remove them and reshape the tab for reuse.

Question #2: No, the linked wires apparently have the terminations already attached (see the photos below the main one).

You can also buy the connectors bare for crimping onto wire lengths of your own choosing.
I've managed to get by with the posted wire lengths so far tho. Sometimes adding a 3" onto a 6" to make the 6" a little longer.
Farseeker is correct, with a little flat screwdriver blade it is not hard to slightly lift the plastic retaining tab and slide the pin out to put it in the correct hole - I've had my share of pinning mistakes smiley
If you get the pin in the crimp housing in the wrong orientation, it just won''t snap into place. Pull it out and rotate it 90 or 180 degrees and slide it back in.

I bought a universal crimping tool which wasn't too bad cost wise....but its main draw for me (being tight) is that it can do many variants of crimp tool, therefore it earns (& justifies) its keep  smiley-lol

It's called an  "Engineer PA-09" (made in japan I think, but pretty easy to source in Europe & I'd imagine the USA too)

Edit: Just found it .....with a video - http://www.precisionhandtools.co.uk/crimping/engineer-pa-09-universal-mini-crimping-tool-for-molex-jst-amp-hirose-jae-etc.html
