Now if there was just a way for me to remember to orient the jack that way...

Oh wait, I've got it...

Now why in the world would you ever orient the jack any other way?

Well, now that you mention it, I guess it's obvious...

Maybe this will help.

Here is the CORRECT way ...


With the +9V for the board at the TOP
Ground at the BOTTOM.


Any deviation from this is WRONG!

Is there a master list somewhere with LED square pad designatio for various other vendors? I have 30-40 pcbs almost finished except for leds cuz I forget which one is which. I know Aion is reverse of PPCB leds. I forget with GCI, DEFX, Zerogiod and *Other pedals?

If nothing else, you can look at trace and see which side goes to the clear. Or, you can use your DMM to see which pad has voltage.

Or to ground.
