Teyleten Robot Max98357 I2S 3W Class D Amplifier Breakout Interface Dac Decoder Module Filterless Audio Board for Raspberry Pi 5pcs

Making my own voice assistant for Home Assistant and these seem to work fine. I was having a little problem with the quality of the audio and I put a better speaker and what a difference it made. I connected it up to an ESP32, added a microphone and status LED, uploaded code and was finished.

This is a cheap easy way to add and I2S amplifier to an ESP controller project. If you are willing to work through the many examples available on the Internet, it can be very rewarding to get I2S up and running. There is even and example that has a work around for I2S so that you can play short, simple music using an AVR Arduino Nano.

Works well. Be sure to not run too much current to them(volume too high). They automatically shut off.

I've got 3 out of 5 working so that's how many stars I'm giving. I wrote my first review as I wrote them off but decided to try one more after tacos and found the rest actually do work.

Works great!

Great little module, works well with ESP32
