Audio audio;

Raspberry Pi can use the HW-044 via the device tree overlay: # Enable I2S dtoverlay=max98357a void setup() Serial

Then use aplay or mpg123 to output audio directly. Despite its simplicity, users frequently encounter problems with the HW-044. Here is a debugging table based on real forums and datasheet analysis. while (WiFi.status() != WL_CONNECTED) delay(1000)
