I have this faulty Android TV Box Decoder unit lying inside the drawer for sometime but reluctant to discard it being the reason the box is made with high quality material, very rigid and heavy. Until one day inspiration strikes me, hey I can actually turn this box into a MP3 player. So I went online and purchase a DIY decoder for this project. Playing MP3 using micro SD card.. This unit also can render other sources like USB/Aux/BT/FM radio
