you need also stereo earphone jack
- dual potentiometer to ajust the volume ,
- 2 caps 10uf for PMWs outputs,
- 3.3 volt regulator to feed microSD,
- 3.7 volt lithium battery (i use mobile phones battery)or better find 5V battery so you can charge it -derict from computer usb
- maybe you need charger plug and ajustable regulator to drop usb 5V to 4 or 3.7 volt
hope this is enought idea to build the player.
