Excellent Value
Fast shipping and works out of the box with Arduino IDE. The amplifier drives a small speaker well.

Good but Hot
Runs a bit warm under load. Make sure you have ventilation if running WiFi and audio simultaneously.

Perfect ESP32-P4 Option

Great for Audio IoT
Used this for a voice command prototype. The mic quality is surprisingly good for the price.
