pinouts of an mp3 player module? Answered
I have an mp3 player module whch i took out from a home theatre main unit. I want to know the use of some features or the pins which are given in it because i am a beginner to electronics and stuff.
I am using it as a player using headphones because it needs amplifier to play in speakers, but headphones work with medium sound.
It has usb and sd card port for input. Also have 3 pushbuttons , play pause, next , previous.
It has the following pinouts.
Basic ones which I know:
These must be for pushbuttons:
P4.4 (but there are only 3 buttons)???
IR (this could be infrared remote control)
These I want to know what are for???
