I've got this module :

googling I have found many schematics each with a different pin denomination/description. Since I want to make a breakout board with all the buttons, leds and other stuff I need help in finding the correct schematics and deciding which components (resistors capacitors etc) are to be bought and where those are to be soldered.
Can anyone please help me ?
Thanks
