Datasheet

If you have a v1 breakout, you can connect to powered speakers/stereo BUT

YOU MUST USE THE INCLUDED CAPACITORS!

For audio devices requiring a 'line level' input, use the included capacitors. These are

polarized electrolytic capacitors, so it matters which way you connect them. Connect the

positive (longer) leads to the LOUT and ROUT pins, and the negative leads to the L & R pins

of the headphone jack or L and R inputs of the audio device. The common (center) pin of the

audio jack should be connected to the AGND pin.

If you have a v2 breakout, these capacitors can be skipped, they are included onto the

breakout board itself.
