DY-SV5W Voice Playback MP3 Music Player Amplifier Module 5W SD/TF Card UART I/O

(The DY-SV5W is an intelligent and versatile voice playback module, perfect for a wide range of audio applications. This module integrates multiple control methods, including I/O subsection triggering, UART serial port control, and ONE_line single bus serial port control, offering flexibility in your projects.

With an onboard 5W Class D amplifier, it can directly drive 4ohm 3~5W speakers, providing clear and powerful audio output.

It supports MP3 and WAV decoding formats and can accommodate up to 32Gbit (4MByte) TF card memory. Update the TF card with audio files easily by connecting to a computer via USB.

The module also features a 3.5mm audio interface, U disk interface, Micro USB download interface, and button mode for added convenience.
