Inputs and outputs
3) Ensure that audio signal source level adjustments are set to minimum.
4) Connect the right (left) positive lead of the audio source to the module
RIN+ (LIN+) pins and the negative lead to the RIN– (LIN–) pins.
5) The outputs are to be configured in the following manner:
a) Connect the speakers to ROUT+ (LOUT+) and ROUT– (LOUT–),
making sure that the polarities are observed.
or
b) Insert the headphone into the onboard headphone jack.

Power up
8) Connect external power supply set to 5 V across EVM VDD and GND pins.
9) Verify correct voltage and input polarity and set the external power supply
to ON.
The EVM should begin operation.
10) Adjust the signal source level as needed.
