Topic: Breadboard-friendly power connectors? (Read 679 times) previous topic - next topic

Hey all,

I have a couple of the connector thingies shown in the attached pic- sorry for quality but it shows the problem which is that they don't fit breadboard power rails.

I know I can jam the wires into the holes, but that doesn't work with stranded wire. What do others do for power connections to breadboard? (No electronics required- I've just hacked an ATX PSU so I have various voltages (3v3, 5v and 12v) available.)

I bonded one of these to a breadboard, and soldered jumper wires to the pins, and inserted them into the rails.

Yeah I was thinking something along those lines... blob of Araldite should do it.

Yip - I got 2 - one on each power rail - can do 5V & 12V on same board ;-)

1. Mount the protoboard on a piece of plastic then add binding posts. Use a wire from the posts to the protoboard.

2. Use male headers on the protoboard. Solder wires to and use female headers on the male  :smiley-sweat:
3. Make small PCB with male headers on the bottom. Mount the terminal block you show on the top of the PCB.
The way you have it in your schematic isn't the same as how you have it wired up!

I know I can jam the wires into the holes, but that doesn't work with stranded wire.


Then use solid core wire - or use a thin-enough gauge of stranded wire that you can tin the ends (and the tinned section will still fit).

I typically do one of the above, and use alligator clip jumpers from the PSU to the board. I generally will run the inputs to the positive and negative rails on opposite sides (so the alligator clips have less of a chance of shorting), then jumper on the opposite end of the board the other rails.
I will not respond to Arduino help PM's from random forum users; if you have such a question, start a new topic thread.
