Datasheet

In the bottom left is an amplifier section, this is a stereo 3W amplifier, with bridge-tied load output.
It's only meant for driving speakers directly! Do not connect to another amplifier, use the
line out for that! Also, you cannot bridge-tie R and L together - if you need only one speaker,
leave the unused one disconnected.
For the amplifier, we're using the TS2012 class D chipset, the same used in this amplifier
board (http://adafru.it/dst)
Speaker connects
On the left are two sets of breakouts for Right and Left. Connect these directly to your 4 or 8W
speakers. Ideally they are 4W 3W speakers or 8W 1W speakers. You will get louder audio with 4W
speakers since the amplifier voltage is maxed out at 5V from the Arduino.
If you have both speakers attached and you're playing loud audio, you may need to power the
Arduino from DC power jack instead of USB since USB can only provide 5W (5V @ 1A) max and two
3W speakers = 6W!
+dB jumpers
The default amplification for the speakers is +6dB. This gives nice unclipped audio from the VS1053
even at highest volume. If by chance you can't amplify the audio (its not normalized right) or there's
some other reason to need a higher amplification, you can short the +6dB or +12dB jumpers to
increase the gain. Don't do this unless you're really sure! You can end up with really heavy
clipping which sounds bad!
