Drill measurements for 3PDT breakout board

[zakco]

When designing a drill template for a build that will use this breakout board, how do I determine the exact distance between the 3PDT switch and the LED bezel for the drill holes?

Measure from the center of the 3pdt to the center of the led?

 

[zakco]

I would, but I don't have one in my hands yet. I'm pre-ordering a few enclosures from Tayda as it takes a while to get them drilled and printed.

That's very helpful, thanks!

Another rookie question…what are the 2 unlabeled contacts beside the other connections?

"IN" refers to PCB input, "OUT" refers to PCB output.

When you use these, you also need to place a jumper across the LED pins on the main PCB, as well as the CLR on the main PCB. Or, if you've already installed the CLR on the main board, then place a jumper across the CLR pins on the breakout board.

If you get the distance from the switch to the LED wrong you can also bend the legs of the LED to get it to the exact position you want. Then set the height and solder it in place.

Thanks for the tips. So far, I’ve only built AION kits and the footswitch board has a lot more going on, including +v. Am I correct in assuming that is for the power supply circuit and the footswitch doesn’t require +v ?

Gotta power the LED but I think Aion has pads for that.
I would advise against mixing daughter boards between ppcb and Aion if you e just been doing kits. They each have their own way of doing things. It's doable but odds are you'll end up in the troubleshooting section before it's over with.

Sorry for the confusion, I’m not mixing ppcb and AION boards, I was just pointing out the differences, specifically that the AION footswitch board contains the power supply circuit. With the PPCB breakout board, where does the LED get power from? Do I jumper from the main board?

The two middle solder pins are the LED circuit and ground

Ah, yes. In fact, I knew that.
I think it’s time for bed

Tenths of a millimeter? Man I'm doing good if my bit hits the box.

I get Tayda to do all my drilling. Which is the primary reason I regret buying boards off other companies.

 

[szukalski]

The real reason I do faceplates is to cover up shoddy drilling I've had to oversize to fit a PCB..

When your bit hits the box every fraction of a millimeter counts!
