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.

@Nishan:
There is number ID for the board.Just ask them for the USB MP3 player board. You can get the board from Kerala Sales also. but I think it is little cheaper in the near by shops. If you could, come to post office road of Thrissur and have a search.

It also has FM receiver in built. In Delhi the kit costs Rs.150/-. One can use Cheep Multimedia Speakers to avoide earphone lisning.
@VU2DED:
Ya now the prices has been reduced over here also. The board now costs around 180 rupees. I think computer speakers are the best for connecting into this player.

I have a no-name player.
The wall wart takes approx 40 minutes to recharge, after which the player says ‘battery full’.
Then it plays for about half an hour maximum, and shuts down.
I would like to extend the play duration.
Thanks.
Sanjeev.

This type of PCBs are available in Hyderabad Gujarathi galli electronic market.The price is Rs.180/- excluding IR sensor & 7805 IC for 5v.A parallel connection available on the PCB for SD memory card slot also.Be careful in wiring the IR sensor otherwise you will damage it.It is a PIC based preprogrammed circuit hence complicated hence do not ask for the circuit.

I got the similar circuit from Bangalore SP road, Modern electronics. Circuit has three output socket (2 “10pin” and 1 “2pin”)
Anyone got the same here are the details.
Left side 10pin socket is for SD and USB connection, last 4pins are for USB marked as vcc, DM (Data-), DP (Data+) and GND. I have not connected the SD card connection.
Right side 2pin socket is for voltage in, clearly u can see the +ve and -ve.
Bottom 10pin socket is for
(1)Speaker Left, (2)Speaker Common, (3)Speaker Right, (4)Track Change ++, (5)Mode, (6)Track Change –, (7)Pause, (8,9,10)then three pin for IR sensor.
The problem here is for me the IR sensor or the remote is not working, dont know whats going on… need to figure out.

@ Anish K.S :
Even without the IR sensor, the player will work.
Hi,
Wat are components required to build the DC 5V REGULATED power supply ?
@Rits:
You need a 6V transformer to stepdown the voltage. Then rectify anf filter it. After that it cab be fed to a 5V linear regulator IC(7805) to get regulated voltage.
Almost forgot…
Howz the mp3 sound clarity.
(good, very good, excellent, bad, worst?)
I am from Vizag Andhra Pradesh I got the above unit. Actually I want to connect to DVD player I have MEPL player so how can I connect D-, D+ to the player if MP3 also how can I connect please give suggestions and connections.
