Wiring up pN64 components, is this correct?

[LionelHutz]

Here is my wiring diagram.

on the N64 pins are:

6= 12v +
3= 3.3v +
4= 12v -

A few questions I have, does the - from the 3.3v connector need to hook up to anything? Where do I hook up my - from the audio amp and 5v fan? Can they just go to ground?

From the screen, will there be a G connection from the V or will it just be V to V on the n64 board?

Am I missing anything else or is anything incorrect? Id much prefer not to fry my board lol.

You have a ground from power going to the screen, so you won't need an additional line from where you get video. I'm not super sure about the power pins. You can bypass those completely if you like, but they are labeled on the board if you want to go that route. If you have issues with the power switch you can connect 7.4v to the 7805 input and 3.3v to a nearby capacitor. Look in buds trimming guide if you want to go that route.

What do you mean power pins?

Also what about the - from the 3.3v convertor, 5v fan, and audio amp? Do I need to solder those anywhere and if so, where?

Anyone?

What revision board are you using?

Depending on what revision you are using you can wire power to the board on the capacitors and chips to ensure they are correct.

The negative lead of the fan can go directly to the ground off of your supply protection circuit.

Your voltage regulator should have 3 wires; your 7.4v input, 3.3v out, and ground. Ground can go right to the same location as your fan negative/ground.


All of your grounds can go to the same point. Just bring one wire from your battery and solder all of your grounds to that from your fan, motherboard, etc.

For my 3.3v convertor, do I want the ground going to the input or coming from the output?

Wire it like it shows in these pics:

I don't understand what your question is. The ground just goes to ground. Are you talking about from the PCB?

Sorry, I should have specified. I am using this step down http://www.ebay.ca/itm/LM2596-Buck-Step ... 5d51b05c1d


Also using this audio amp: http://www.ebay.ca/itm/Small-PAM8403-5V ... 51caee2c49

Do both G need to be connected or just one?

I have no experience with that type of regulator. Seems to be a lot of overkill to save a few bucks instead of using the pth08080w.

But all of the grounds go back to the same point basically. You need ground from everything that has a ground. regulator, amp, motherboard, etc.


That dc converter you linked seems to be quite large a component to be putting inside a portable. IMO, you'd be much better off using something smaller like the one I mentioned and has been documented heavily here to work with no problems. Not to say that won't work, just seems a bit much to have a display you won't see.
