A full open source mp3 player featuring a PicMicro and the mythical decoder VS1011b from VLSI. Schematics, C firmware source, pcb layout and bill of material are available for download.... sorry, the only missing part is to assemble the whole project, well that's up to you.

It must be stressed that FAT32 to handle mmc memories is made available. If you want to build it up, or you just want to have a look to the (well done) firmware and/or schematics, don't let this project slip through your fingers.
