I am going to design motion activated solar powered mp3 player. So my 1st task is design mp3 player.
I looked and bought one that was 2.5usd, it has used only one IC.
attached image.
I checked the IC and read it and searched in google. But I couldn't find datasheet or schematic.
anyone know one chip that has this functions.
1.mp3 decorder
2.USB
3.sd card connections
4. button connections for PLay,pause , vol+,vol-
5. earphone output
attached image is the pcb of my mp3 player, that chip has all of this
