That link still shows the old incorrect diagram. Where is the new diagram?

The old diagram and the new diagram show the same wiring for speaker and headphone output which according to Helder are wrong.

Does the audio on this board go through the usb connection or does it use the GPIO pins? I have a hat that I want to use for wifi/bluetooth and I think it uses one of the same pins the audio is routed through in wermy's guide. Would that even be a problem? Can the same pin be used for two different things?

@a3k4 's link I provided was updated to fix some polarity issues that can cause some damage, I did not get as far as hooking up audio yet. I took it upon my self to use the very limited program Paint (since I don't have access to photoshop at work) and apply the fix indicated by @helder on his thread. Hopefully this is correct, feedback is welcome.

Did you upload the wrong file or am i blind? Cant see a difference...

[hueblo]

I uploaded the wrong image but noticed some other mistakes, will have to use paint to fix it again!


I just uploaded what I believe to be the correct one.

The audio I linked to in the other board thread should apply here. This is how I wired it to work with the original headphones and have the speaker work and cutoff once the headphones are plugged in. I added the GND pad near the audio pads for convenience and if people use USB Audio instead of the GPIO PWM method.

In fact the GPIO pins can be changed to whatever you have available and want to use, just follow the guide in Guides section for PWM Audio and you HAVE to modify the config.txt for PWM and also the GPIO pins you plan to use.

My board facilitates the works of alot of things BUT it doesn't program the Pi to do what it needs to, that's where the user comes in. PWM Audio needs to be added in config.txt before it works and a volume potentiometer wheel is recommended and cheap enough to get.

Thanks Helder, this is great! Its going to save me a lot of time in my build and will result in a much more clean and straightforward product. I would like to pre-order one. Do I just click on the paypal link next week when they are available?

I tried to do the the preorder as well but it sends me to paypal but order is unavailable. I hope it will be back to order soon. Thanks

@hueblo Question, what exactly is the purpose of the Pololu Mini MOSFET slide switch protector and Main On/Off? Is this some setup to work with the original gameboy on and off switch? I haven't been around for a while and noticed it in your diagram. Wanted to make sure I wasn't missing something logically since I was going to post asking if anyone knew about a 3rd party version of the DMG on/off switch (building a non-salvage game boy zero). Thank you for your time and response.
