I found an mp3 decoder completely ported to the F103 MCU. It's the Helix decoder, different than the one used in the 8266 at the top of this thread.
I found it in the link to one of the taobao boards. It was a board with 64KB, not sure how much of that it comsumes:

I haven't look at the details yet, so no idea if it uses the DACs in that chip, or the i2s (may be the case...).

Any way, whenever I have a chance I'll test this out in one of my RCT6 boards, as those actually have 64KB of ram, so should be enough.
This may be a good option for many, as those boards can be had for the same price as a VS1003 or less, and instead of 2 boards you use only one and a little amplifier.

Hi. I know this topic is old but has anyone ported the Mozzi library to work on stm32? Would love to play around with it if it has.
