    Oh. Wait you mean to power the mp3 module from the arduino? Don’t. Instead just use any usb charger to power the MP3 player. If you follow my exact schematics you use relays instead of the buttons on the MP3 player. And the voltage on the arduino shouldn’t matter. As long as the relays can work on 2.7v.
    Hope this helps more than my previous answer.

    I used a 5v version of arduino. I think I used an UNO which uses 5v as standard. 
    What arduino model do you use?
