This MP3 voice broadcast module provides audio playback functionality for electronic projects, supporting common formats like MP3 and WAV without the need for external storage.
In practical applications, such as DIY security systems or interactive toys, it allows for easy voice announcements triggered by serial commands or IO inputs, helping streamline project integration and reduce complexity.
- Supports MP3 and WAV formats with sampling rates up to 48 KHz for clear audio output.
- Features 64Mbit onboard Flash memory, eliminating the need for memory cards.
- Includes a 5W Class D amplifier to directly drive 4-ohm speakers.
- Offers UART serial control for functions like play, pause, and volume adjustment.
- Provides IO trigger options for up to 255 tracks via 8 ports.
- Supports One Line single-bus control for simplified operations.
With a compact size of about 4x3.5cm and 5V operation, this module fits well in space-constrained designs for hobbyists and developers building custom audio solutions.
