MP3 player barely larger than an SD card

If your board fabrication and soldering skills are up to it, you can make your own tiny MP3 player. This rendition is just about half again as large as a standard SD card, whose slot is on the bottom of the board seen above. The heavy lifting is taken care of by a VS1011 MP3 decoder which also has its own stereo headphone driver on-chip. There’s no display and it seems that most of the 4k of program memory on the PIC 18LF88 is being used. Too bad, we’d love to take this to the next level, attaching it to the head unit in a car and spoofing the communications as if this were a CD changer.
