Example 0: Without an Arduino
As stated at the end of the hardware hookup, you could simply power the board up and send an audio signal to the Qwiic Speaker Amp. When everything is connected and secure, power the Qwiic Speaker Amp up and start playing the your favorite track!
Note: The default gain for the TPA2016D2 is 6dB. For a larger gain and a louder volume from the speakers, you will need an Arduino microcontroller to configure the gain settings.
