Mini MP3 Player Module For Arduino
Mini MP3 Player Module for Arduino – DFPlayer Compatible
Overview:
The Mini MP3 Player Module is a compact and low-cost MP3 player solution with an onboard microSD card slot and speaker driver. It can play audio files stored on a microSD card (up to 32GB) and is ideal for adding sound effects, voice feedback, or music to Arduino and other microcontroller projects. The module supports both serial control and standalone operation.
Key Features:
Built-in audio decoding chip: Supports MP3, WAV, and WMA formats
Supports microSD cards: FAT16/FAT32 up to 32GB
Built-in DAC and amplifier: Can directly drive an 8Ω/3W speaker
Serial communication interface: Compatible with Arduino and other MCU boards
Low power consumption, compact size
