Actually. I shared the info for you as I know that you (and your better half) are F-18 intoxicated ! 
Hint: Anniversary present ??

Hey Ray, you're totally out doing yourself and making some awesome additions! Keep things going!

John

That looks AMAZING!

Thanks.

I will prob build my own circuit and keep it simple instead of using modules.

Will put the mosfet between PS Negative and the Negative busses so i can use the Source and Drain of the mosfet just like normal.



Thanks again for sharing your input, really apreciate it.

Thanks

what FDS can not  post their own stuff ?

I will add a heatsink and top it with 4.5Amps. I will install these on a metal plate and check the temperature.
But with many, i can devide all my backlight of around 20Amps in total.

Circuit will be pretty much ->

VIN -> 5V+ from power supply
GND -> - Negative from power supply
V+ -> My 5V+ Backlight positive (bulbs)
V-  -> Connect Negative cable from my Negative Bus where ALL my negatives are connected.

Thats the plan.


My only question left is if i can take BOTH the GND and V- From my negative Bus?

That way i can have all negatives still in one bus

No, that won't work. That module is a low side switch. Here's a better picture:

You can see from the photo of the underside of the board that V- and GND are not the same. V- on the board goes to the MOSFET which then switches it to ground.

If you Google for IRF520 you should find a bunch of application notes that might help you understand how the MOSFET works for different applications, and how to use it. That module is (probably) the simplest low side switch you could make.
