Topic: Where to buy breakout board for 12v expansion?

So I want to run 4 fans and an LED off the fan port of my RUMBA that only comes on when the printer is in motion and I don't want to do a crazy number of splices.  I forget if this is fan0 or fan1.  Is there somewhere I can buy a "breakout board" like the one in the RAMPS sticky post?

Pictures in the first here: http://www.soliforum.com/topic/2816/how … ontroller/

I really want to avoid soldering.  Screw terminals would be even better.  I've been searching digikey with no luck but I'm not sure I'm using the right search terms.  Any suggestions?  Thanks.

Fan1 will come on when a heater is activated or the motors move. You can use wire nuts for the splicing. These are what I used to make my own wire bundle. Then I just put some heat shrink over the wire nut.

Fan0 is g code controlled

Ya, it must be fan1.  I'm not at my printer now to look.  But what if I want it to be neat and pretty?  I'm working on another build (see projects forum) and I am putting the board at the bottom of the printer and I might put a clear cover over the whole thing to show off the wiring and add some more LED to make it look nicer.

I'm still looking for a breakout board/ sidecar board/ expansion board that I can use to expand 12V screw terminals for several connections.

Or make your own if you want small and pretty with these

Ya, that looks like it would work.  The ones ward posted are what I had in mind, but I'm not interested in making my own or soldering.  With this one, it looks like I just put the + and - 12v wires into one terminal on the end and all the other are then energized, right?  So the connections underneath are already done?

Thanks.

I was thinking the exact same thing but I would think if you spent more that the 20 seconds I did searching you'd be able to find the small ones already connected the way you need.  The ones Tim posted I have worked with and they are big and clunky.  Great on the firewall of your hot rod but not the perfect solution for what you stated you were looking for.  Either way you'll come up with whatever works for you.

Have Fun!

I did, in fact, spend upwards of 20 minutes searching for this before making a thread.  I'm pretty out of my element here and I don't even know the correct technical name of the part so if anyone has any leads I would appreciate it.  Thanks.

When I get some time I will do some searching I have my own project that would benefit from the same thing you are looking for.  It may take me a few days before I get around to it though so if you come up with anything let us know.

No, each strip is independent. You're probably looking for power distribution blocks:

Re: Where to buy breakout board for 12v expansion?

Something like that might work, although it says that particular one is for wires 20 gauge and larger as it has 6mm holes.  So the standard 22 gauge wires from fans or LEDs might slop out.

I assume you would just buy 2 of these are wire all your + into one and all your - into the other.

I think typical screw terminals are probably better.

That's the one I am looking for thanks Tim.
