Yes you can just solder wires where the barrel plug attaches to the board at and then add the switch as already mentioned.

If it was an internal power supply I could splice a molex connector or something similar. But this is a wall wart type supply that delivers 24vdc through the barrel adapter, which is soldered to the board.

So other than soldering leads to the female barrel on the board, I'm not sure what my options are.

The wiring of the switch and fan after I tap into the power seems pretty straightforward. Thanks again

Should I just solder a few lead wires to the barrel adapter?

Thanks for the response


Just use a meter to find the 24 volt line from the power supply and splice a wire to that line. Then connect the newly spliced wire to a switch newly mounted in the case. The fan power lead connects to the other side of the switch. The fan ground will be spliced in to any of the ground lines coming from the power supply. Make sure the fan is a 24 volt fan. The reason for the switch is you don't want it running on the first layer.

I'm trying to figure out the best place to draw <0.2A on a da vinci mini PCB for a layer cooler fan. The empty 3 pins without a header marked "Lighting" (bottom right) provides 24v, but I don't know what the max draw is. I figure a few LEDs take less than a fan, so I'm hesitant. Additionally, I don't believe the "FAN" pins are wired up at all.

If I want to tap into the main power coming off power supply, how would I do that? The mini has an external power supply, with that barrel plug adapter shown.

My electronics knowledge is pretty basic, so any help would be appreciated.
