Need advice and clarification on Wire Connector Tutorial

<< < (2/2)

Inigo Montoya:
With enough work, I was able to find everything I needed at polulu.com.  The website was very friendly and everything was easy to find with no fuss.  Score +1 for Polulu and -1 for Digikey for usability.  Taking a close look at the connectors at both Polulu and Digikey, it seems that they are incompatible.  It's a good thing I didn't buy at Digikey, because they didn't seem to have some of the housings like the 1x1.  Here is a slightly more comprehensive list of links from Polulu

Female Crimp Pins:  http://www.pololu.com/catalog/product/1930
Male Crimp Pins:  http://www.pololu.com/catalog/product/1931
1 Pin Housing:  http://www.pololu.com/catalog/product/1900
2 Pin Housing:  http://www.pololu.com/catalog/product/1901
3 Pin Housing:  http://www.pololu.com/catalog/product/1902
4 Pin Housing:  http://www.pololu.com/catalog/product/1903
5 Pin Housing:  http://www.pololu.com/catalog/product/1904
6 Pin Housing:  http://www.pololu.com/catalog/product/1905

This is sounding like a plug for Polulu, but it's not, I just like how easy to find everything is on their page, and the prices seem reasonable.  I haven't bought anything yet, but I plan to very soon.  Can anyone else share their adventures in purchasing pins and housings?  Cheaper/better suggestions are welcome.

Ok, glad you did find what you needed.
DigiKey is great but they have many, many more part choices and therefore makes picking the correct parts difficult. I use DigiKey for parts at work (RnD) but start with info from the manufacturer then go to DigiKey with the manufacturer's part number.

Pololu is a great resource for hobbyist and I do buy stuff from them. I like their selection, quality and prices (I have no other connection).

Good to know you found what you were looking for... I too was curious and spent an hour searching the other day, but didn't find it on Digikey/Mouser

Pololu, among other things, too, has the best documentation of consumer-level hardware sites.

Pololu is very nice. They have pretty good documentation for most of their things, and they go through the hard work of figuring out what things will work together, so you don't have to.

Pololu does *not* have the same level of documentation as "industrial" sources, like data sheets for hardware components (from TI, IRL, STM, etc,) or mechanical CAD drawings for parts (from McMaster or similar.) They are a lot better than most hobby/RC shops, though, where even the most basic measurements are often not well specified.

Anyway -- I'm a fan of the Pololu pre-crimped wires, and their various housings. They snap together easily, and you can get your cable going and be on your way without any additional detail work. Stripping/crimping your own cables saves a few cents, but take a lot of time that I'd rather be spending on something better :-)

Get a couple of "rainbow packs" of pre-crimped wiring:
and a few different sizes of housings:
and off you go!
Personally, I prefer to use female/female cabling, and use male headers on my circuit boards. This of course doesn't work for hooking up to, for example, an Arduino, where M-F wiring might work better. YMMV.

Inigo Montoya:
Well, this isn't really a plug for Polulu, but my shipment has arrived and I've been working on my electronics, and I have to say I couldn't be happier.  Thanks for all the advice guys!
