I'm have a project of the control a few leds and relay, so do not have pins available for the utilization of the Mp3 Player.
This board can be utilized only with UART communication? pins TX RX.
No. That MP3 Shield use a bunch of digital pins and does not use the UART pins (RX,TX) at all.
If you look at the Arduino part in the bottom left corner of the schematic you will see what Arduino pins are connected to components on the MP3 Shield. Looks like D2, D6-9, and D11-13 are used. D3 and D4 may also be used if the solder jumpers for them are closed.

Ok johnwasser, thanks for reply!!
I will try disable the jumper and release the pins 3 and 4.
I need of 10 pins of the arduino.
