Title: Good Wire to PCB Option?
Post by: joja01011 on Mar 26, 2009, 01:21 am
Hi I'm trying to figure out what route to take for the connections I need to make for my PCB I'm going to make.  I'm going to need about 20 points for wires to connect about 22GA to my PCB.  A power supply and GND wires will have to be a little bit bigger.  I looked on Digikey and was overwhelmed with the options, but I was looking at something like these
Would that be a good choice?  I need to be able to remove and connect the wires if needed from the PCB.  I'm not putting through very many volts or amps, 9 volts and under an amp.

If you need more info let me know, any help would be apreciated!

That looks similar to what one of the Arduino compatable vendors used:

See also: which includes some part numbers...

The big decision is how small your want the connectors.  getting them on 0.1 inch centers is possible, but seems to be pricier than the "normal" size of about twice that.

Screw terminal blocks are the devil.

0.1" headers, like the ones used on the Arduino board itself, are a fine choice. They are available in a wide variety of styles -- personally, I like the shrouded ones with the alignment keys, either with or without the locking ears.

My favorite connector for general hacking is, however, the humble d-sub. Standard and high-density d-subs are rated for 5A per pin, and come in sizes from 9 pins to 78 pins. Mixed-signal d-subs can include high current contacts rated up to 40A, coax contacts, and 3kV high voltage contacts. They are available in every grade from the cheapest IDC off-brand crap to environmentally sealed & EMI filtered gold-plated mil-spec hawtness. Jumper wires for 0.1" headers will fit on standard and high-density d-sub pins for easy commonality during debugging.

Some good suggestions here. I use the standard 0.1" headers that are used on the Arduino and many other similar products. There are a couple of things around that will help you greatly.

This page shows a variety of cables and jumpers. The 75 piece pack of prototype board jumpers is interesting, but I haven't tried them on the headers used on Arduinos.

Sparkfun at have a male to male jumper wire which I have and I know works. They also have a female to female one as well.

I find these an essential item to have on the workbench.
