[SOLUTION] Re: VS1053B vs PAM8403 (Class D amp)

Ok, I nearly got it with this circuit:

--> "Schaltplan analoges Teil"
There is some - quiet - random noise left, but I'm sure this is caused by the bread board.

Hello, I know a similar topic exists here: http://www.vsdsp-forum.com/phpbb/viewtopic.php?f=10&t=2017&p=10414&hilit=pam8403#p10414 But this didn't helped me out: Simplify circuit: STM32F103xxx connected to a VS1053b dev board (this with SD card onto it) VS1053b phone out -> PAM8403. Driven with a Li...

Re: VS1053b from the scratch - two questions

The ideas are open end... I like this. I'm going to produce about 10 devices for friendly families (and one for my younger daughter) . This is my first test phase, so I can modify the hardware and firmware if there are faults easily ("Bring your player and some beers, you'll get fancy new features!"...
