DY-SV5W MP3 Voice Playback Module (SD Card/Flash)

If you need your project to talk, play music, or make sound effects, this is the most versatile module available. It features a built-in 5W Class D amplifier, meaning you can wire a speaker directly to it without any extra parts. It plays MP3 and WAV files directly from a MicroSD card. The “Magic” of this board is the Red DIP Switch block: by flipping these 3 switches, you can change how the board works. You can set it to play a specific sound when a button is pressed (IO Trigger), control it via Serial commands from an Arduino (UART), or use it like a standard MP3 player with Play/Pause buttons.
