If you’re using Adafruit’s MAX9744 20-watt stereo amplifier board in a Raspberry Pi or BeagleBone Black project then check out this simple Python library to control the amp’s volume over I2C. With 20 watts of power this little amplifier has more than enough oomph to really make your speakers shake, and digital control of the volume opens up cool possibilities for projects. With a few lines of Python code you can set the volume of the amplifier directly from your Pi or BeagleBone Black. Build a headless music player, boombox to play podcasts, or anything else you can dream up. Check out the library’s home on GitHub for details on how to connect the board to a Pi / BeagleBone Black and install the Python library.
