[For Sale] $7 Game Boy Zero Controller PCB W/ Optional Audio $20 (Worldwide) SOLD OUT

[Helder]

I could add some Test points but I don't have all that much space on the board so you would have to be specific about which pins exactly.

I have designed a breakout board for usb, it has a male connector so it's like the flash drive connectors and it has Screw terminals for easy cable insertion. You can use anything you have on hand but for those who don't this a is a cheap alternative plus it can be useful for other things.

I ordered a few for myself and connectors too so I can sell a few off if people don't want to buy the parts themselves and assemble it.

Do you have any price currently set for the all in one board?

[Spleen21]

First of all forgive me if i have it all wrong. Just trying to offer up ideas.

I was thinking if there were any left over I/O pins on the atmega (not sure how many you've used so far), perhaps they could be broken out and used for anything the user might need. Perhaps LED's, or extra switches/buttons. I was thinking perhaps the USB port pads could be shifted across a wee bit and some general purpose I/O pads could be placed next to them for easy access.

Again, I've never designed a pcb before, let alone one in such a confined space so excuse me if im just not getting it. This board is already fantastic and saves the rest of us a huge amount of work and space inside the GB.

I will be ordering!

Thanks again

For those who are still having some noise I found the manufacturers instructions for the audio chip Helder used and it recommends using ferrite beads inline with the speaker positive and negative and that should counter any emi in the system causing noise

Should I put them right before the speaker?

Yes right before the speaker

They will be $35.

For me to add anything else I need to have free space to route traces and from you want it's not possible but there are a few I have a little free space that can have a test point but I already ordered the boards so no way to make changes until another order in the future.

Thanks Helder

What is the Ground below the Pot's for? Also, can you diagram/talk what the audio pads at the bottom go to?

Would it be possible to extend the board out to the bottom right? The original headphone jack can be cut down smaller, giving you room for more circuit board real estate.

In the first post of the thread there is a picture there that shows how to connect the volume wheel to my board. If that wheel isn't connected to common Ground there will be audio issues so I added the pad there so that the 5 points on the wheel go to the pot 1-4 points and the ground .

I'll also have a diagram for the install once I get the boards in.

Has the revised audio board received any updates or changes like this? I also noticed the all in one has a designated headphone and speaker pads.
