Raspberry Audio Board

Post by Noob999 » Sun Nov 05, 2017 9:13 am

Hi @All,
first thanks for this excellent Board. I have learned so much. My Name is Tobias and I am from Switzerland.

Currently i am working on a 5" Portable. After investing a lot of Time (And Money ;)) i didn't found any good and small All-in-One Audio Solution. So i came up with the Idea to develop my own Audio Solution.

After investing much more Time ... this is the first Prototype:

It contains a PCM 2704 USB DAC and TPA2016 Audio Amplifier all the Pins for external Buttons and i2c Control of the Amplifier are routed to the PIN Header.

Also it contains a Headphone Jacket which switches automatically to Headphones as soon you plug in

It sounds absolutely amazing i am very happy with the board

Looks cool. Where and how much? :)

One small suggestion: if you're selling it for use on handhelds, it'd be nice to have the headphone jack, USB port and header block depopulated - it would make the board more compact and easier to locate inside a cramped build.

Thanks for the Reply ... as i said it‘s just a Prototype.

I want to do following:

- Replace Caps with SMD Ones
- Replace USB Connector
- Make it as small as possible ;)

I thought about JST Connectors for all external Connections or do you prefer PIN Headers ?

I really thougt more people are interested in this :(

Nobody else had Problems to find a Audio Solution for their Portable ?

I have done a lot of Research and didn't find anything which combines a USB DAC and a good Amplifier.

What are you using for your Portable Projects ?

Most people are using the AIO boards that already have the sound issue solved. I would have killed for your solution about a year ago but now not so much to be honest. The AIO are very space efficient and most rather pay the extra buck just to be able to do it hassle free.

But don't stop working on it just because of my comment. It's an elegant solution for people that can't get an AIO board (they can be hard to get at times) and I'm sure people will need it, you just can't expect a reply in a week :P.

Although I agree it can't really beat the AIO boards as far as gameboy zero projects go, this is great for other custom tablet-style projects. Those are just harder to accomplish and not as popular as the game boy zero is.

I actually made a similar board with amp and all but it was for prototyping and had no large caps or sockets, just some solder pads. Why no integrate your design into another board?

Don't contact me about obtaining my board files (as you will not get them). Don't contact me about any of my boards if they are sold out, they will be restocked as soon as I can get them.


Don't support thieves like ckliang who copied my AIO to resell and is now cloning the mintyPi, support the original creators and not the thieves!

That's exactly what was the Original Purpose ... we are currently working on a "bigger" Board and this Audio Board is Part of this Project ;)
