Great looking project. Is this going to be a product?
-
Yes. Once I get some kind of certification from ibiquity, then I may be able to sell it as a whole product. The hardware and schematics will be open source
I also plan to make a portable version with the same functionality, but I have no clue on how to add a charging circuit / battery to the whole mix:

I able able to draw very low current using the Snooze library, so standyby time should be great, and the whole circuit draws about 150mA when running with earphones plugged.

Did this thread look interesting if you saw it?
I got an MCU board from onehorse - in a spot smaller than the size of a grain of rice from other version he dropped in a LIPO charger with LED for the board that already ran on one.

Interesting post. I think I read up on the MAX1551. I will post more in the technical support forum for any other issues. I will probably need something that can give me just 3.3v from the battery, and can give me a battery level via I2C.
Thanks!!

What CAE program did you use for the PCB design?

I'd like to see the PCM5122 code, especially the part where you send the DSP configuration over I2C

I used Eagle for PCB design and then Fusion 360 for the 3d models
