ESP32 Audio Output with I2S DMA and the MAX98357A Class D Amplifier

Hey Everyone, we’ve spent a couple of videos getting audio into the ESP32.

I2S input - https://youtu.be/3g7l5bm7fZ8 ADC input - https://youtu.be/pPh3_ciEmzs

In this video, we’re now going to switch it up a bit and get audio out of the ESP32!

We're going to using the MAX98357A breakout board from Adafruit.

This is a class D amplifier with an I2S interface which is great because it means our audio signal stays digital all the way up to the speaker output.

You'll need a speaker to use the board with at least a 4ohm impedance and you can get up to 3W output.
