a variety of control modes, I/O control mode, serial mode, AD button control mode.fully supports FAT16, FAT32 file system, maximum support 32G of the TF card, support 32G of U disk, 64M bytes NORFLASH.24 -bit DAC output, support for dynamic range 90dB, SNR support 85dB.In this tutorial, we will see how to use this module with Arduino. A Special library is published by DFRobot on GitHub.īy using this MP3 Module you can use it in many applications like Train Announcements in Railway Stations, Fire alarm Voice Prompts, Car Navigation Voice Broadcast, Voice alert Blind Stick and many projects that need voice-based alerts. This MP3 Module can work standalone or you can use any Microcontroller like Arduino via UART Ports (TX & RX). It has an SD Card port and reads the MP3 files from the SD Card. Additionally, you can use an audio amplifier like PAM8403 to boost the Audio signal. You can connect a 3-Watt Speaker directly to the Module. DFPlayer Mini (or) MP3-TF-16P Module is a tiny low-cost mp3 module with inbuilt Amplifier.
