Last day I bought a USB MP3 player board from a local store in Thrissur. This board can read MP3 files from a USB thumb drive and play it for you.
The board circuit diagram is so simple that there are a very few connections. some of the connections are
- IR sensor connection (3 wires - IR data, VCC, GND)
- USB socket connection (4 wires - VCC, D-, D+, GND)
- Power supply 5V (2 wires - VCC, GND)
- Audio Out (3 wires - Left, Right, GND)
- Switch (4 wires - Next, Previous, Play, Mode)
The other main features are an built in FM receiver and also an remote control. The player can read up to 1999 songs. I have not tried any other music formats other than MP3.
The main attraction is its cost. The board cost only 250 Rupees ( 5$).
If anyone needs the connection diagram of the board please do contact me 
Here are some screen shots
Note(Nov 28, 2009): This is not an open hardware project. Please don’t ask for circuit diagram. I actually bought this circuit board from a local store. The connection details are so easy. The board has markings on it for the connections.
