This voice prompt module combines an MP3 playback chip with a built-in speaker, allowing it to operate independently with just a power supply, battery, and buttons, or be controlled via serial commands. Supporting MP3, WAV, and WMA formats, it has playback with clear sound quality, thanks to a high-quality DAC output. You can connect this to a Raspberry Pi, computer, or other microcontrollers!

With 16MB of internal storage, it can hold plenty of MP3 files, and it operates effectively across temperatures from -20 to +70, making it suitable for various environments. The modules design gives easy control through basic buttons or serial commands, and its TTL-level serial communication connector makes putting it into your project much easier without complex programming.
