MP3 Decoder Board with Amplifier 3.75.5V TF and USB Audio Player Module Compact Playback

Compact MP3 decoder and amplifier module for easy audio playback from TF card or USB flash drive. Designed for low voltage systems, this board decodes MP3 files and provides amplified audio output for embedded and hobby projects. Key benefits Simple playback from TF card or U disk: insert a micro TF card or USB flash drive containing MP3 files and the module will decode and play audio without a separate player. Low voltage operation: runs on 3.7 to 5.5V via Micro USB power input, making it suitable for singlecell lithium battery projects and common 5V systems. Integrated decoding and amplification: onboard MP3 decoding and amplifier stage reduce the need for external audio processing or amplification hardware. Compact and easy to integrate: small PCB footprint fits into portable devices, toys, kiosks, or custom enclosures. Broad compatibility: supports standard MP3 format and common storage media types used for audio playback. Features and attributes Function: MP3 format decoder and audio player with integrated amplifier for direct audio output. Input options: micro TF card slot and USB port for U disk playback; power via Micro USB connector. Voltage range: 3.7V to 5.5V operating range for flexible power sources. Material and build: standard printed circuit board with electronic components for reliable, long term operation. Performance: real time MP3 decoding and amplified output suitable for small speakers or line level inputs. Why you need this module Eliminates the need for a separate MP3 player and amplifier in basic audio projects. Saves space and component count when building battery powered or compact devices. Speeds up prototyping by providing plug and play audio playback from common storage media. Typical applications Portable speaker and media player projects: add MP3 playback to battery powered speakers or compact music boxes. Embedded product audio: play prompts or background music in kiosks, displays, toys, and consumer devices. DIY and hobby electronics: integrate simple audio functions into microcontroller projects, home automation units, or learning prototypes. What to consider when using this module Ensure audio files are in MP3 format and stored on a compatible TF card or USB flash drive. Match speaker or line input expectations to the module output level; for larger speakers or higher power, an external amplifier may be required. Power the module within the specified 3.7 to 5.5V range using the Micro USB connector. This decoder board provides a compact, low voltage solution for MP3 playback with convenient TF card and U disk support and onboard amplification for straightforward integration into a wide range of projects.
