It would be a bit easier for most of us here if you posted in english as that is what most of those here use a a language for exchanging ideas and asking questions.... but google translate does a decent job of giving the gist of what you are asking. As Gerald replied, you need only provide 5V to the board to power it either via the DC input jack or via usb. the i2s interface *is* available on the expansion headers, but bear in mind that you'll have some software work to get it configured as i2s and at the correct rate. The Software reference manual shows which pins carry i2s (when the proper pinmux is set / the right overlay loaded) you may also wish to refer to the audio cape pin usage for more details. http://elinux.org/images/1/11/Audio_Cape_B1_Schematic.pdf. Also note that i2s is connected to the HDMI parts on the Black, so you probably will be required to disable the HDMI framer to make use of it.
