MP3 Board Testing

I got one board assembled and working on testing it. The mic portion works as it did on the mic boards and the amp works well. I had to get out my 12V 6A power supply to test it. I think I will lower the gain on the mic stage, a little bit of hiss gets through.

I tried the MP3 portion and I am not getting any audio. I am working on trouble shooting that now. It seems the Arduino is working as it should. So next to check is the memory card and then the MP3 ic.

There are some modifications that I need to make to the board but nothing major.
