Voice Module with IO Trigger / Mini MP3 Player Module 5W
Description
Voice Module with IO Trigger / Mini MP3 Player Module 5W
The module is a smart sound module with an integrated MP3 and WAV decoder, a 5-watt Class-D amplifier, and 32 Mbit flash memory for audio files. It can be controlled via various modes, including Arduino-compatible UART serial data, using a library such as `DYPlayerArduino` to control playback. You can load audio files to the internal memory via USB cable and directly connect 4-ohm speakers.
