Actual wiring diagram

[Cannikin]

Hey guys, I'm playing around with Fritzing and putting together a real wiring diagram. It can also convert this view (known as the breadboard view) to a schematic, but that probably isn't as useful for the layman:



Here's the Fritzing file: gameboy_zero.fzz

It's missing the screen and a couple external USB connectors, but pretty much everything else is there. As you can see the sound section is the most complex, but I think this covers everything: changing the volume for both speaker and amp via the build-in volume knob and then disconnecting the speaker when the headphones are plugged in.

I'll keep this main image updated as I make changes and additions.

Edit 2016-05-21: added download file

Thanks. This will help a lot with my wiring.

Full disclosure: I'm still in the process of wiring everything for real, so there's no guarantee this will work as shown right now! I'll keep it up to date and be sure to post my final working version.

If you use a USB audio to the usb hub, would't you lose the ability to have a USB slot for keyboard inputs? I only have three places for USB without the audio USB, 1=teezy, 1=wifi dongle, and 1=spare for keyboard if needed.

I'm not using a Teensy, I'm gonna use the GPIO pins for input. With the three port hub one is permanently going to USB audio, the other two will be expansion. One will be external (in the "Ext Connector" spot), the other will probably be in the battery compartment.

If you used wermy's 4-port hub then you'll be good even with the USB audio!

Great, I downloaded this a while ago, but never got around to actually testing it.
How did you get those special parts into fritzing? Is there a source for those?

Had to make 'em myself! When I get near my computer I'll attach the actual Fritzing file and hopefully it'll include the parts. Otherwise I'll figure out how to export them.

Just added the .fzz file to the first post! It's got the diagram and then you'll get all the custom components too. I haven't created the proper schematics for all of them so don't trust those yet. But Breadboard view should be good to go.

Have u completed your circuit yet and confirmed working? Curious because I was going to try it.

Not yet...it'll probably be a week at least. I'll update the post here when I do!
