Title: Mix 12V and 5V with pacled64
Post by: herve on February 11, 2015, 11:56:15 am

Hi all,

First I'm sorry for my poor English (French Inside  :dunno), but I search a reply to my question and the only forum which I find is here :angel:

Well, I realise my first arcade cabinet and I would like a control panel with a control of led for sticks and buttons.
So I have bought pacled64 from arcadewolrd (better place I think for my country) with 1 pacled64, 2 illuminated joysticks 12V power, 16 ultralux RGB illuminated arcade buttons, and some chrome effect illuminated buttons 12V power.
I would like to power the pacled64 by 12V and connect all leds from buttons and joysticks to it. I had not data sheet, and now, I see a big problem : RGB illuminated arcade buttons have 5V power!

So, I would like to know if it's possible to mix 12 V and 5V powers (I know it's possible to use two pacled boards but it's very expensive with the price of the card and the shipping). I do not have much knowledge in electricity and electronics, so i take an idea from pacdrive web site in the part called 'Advanced Connection Methods'  : http://www.ultimarc.com/pacdrive.html (http://www.ultimarc.com/pacdrive.html)

So Is is possible to realise connections like in the attachment or is it crazy  ??? (Grounds from 12V and 5V power supplies are connected)

Yes, that's possible! As long as +5V and +12V has common ground it should work fine.

THANK'S A LOT !!!!! :applaud:

I'm very happy from your reply   ;D  I was already imagining not control 12V powered leds... :banghead:

Just a last point. If I put 5V to powered the pacled64, an external power for 12V leds with a common ground, it shoud work fine too ?

Ok... wait a minute. The PacLED requires +5V. Right? That means you can not power the PacLED from a 12V power source. So the ineversion of the picture is the correct one. (Assuming the PacLED requires 5V).

Yes, do NOT connect 12V directly into the PacLED!

Tested today !

I use 12V external power and 5V internal power delivered by pacled64. It works perfectly!

Okay don't put 12V to the PAC LED. Use a relay board for anything over 5v or you will burn the Pac LED up
