DFPlayer Mini MP3-TF-16P Library Support

This module comes in two version. So, choose one from the libraries below based on the board you are having:

These libraries make it easy to play tracks, control volume, monitor busy states, and manage playlists.

Getting started with the DFPlayer Mini MP3-TF-16P

The DFPlayer Mini MP3-TF-16P For Arduino is a small  with an simplified output directly to the speaker. The module can be used as a stand alone module with attached battery, speaker and push buttons or used in combination with an Arduino UNO or any other with RX/TX capabilities.

Hardware Requirements

For this tutorial, the items needed to run this project are:

  1. Arduino Uno
  2. Mini MP3 Player
  3. SD Card
  4. Male to male jumper wires
  5. Resistor 1k ohm
  6. Speaker

Wiring Diagram of DFPlayer Mini MP3-TF-16P to Arduino Uno

After complete your circuit, connect your Arduino Uno Board to your computer via USB Cable. You can see the LED on the MP3 will on. Make sure that the SD card had been installed in the mini MP3. The format of the song must be in MP3 file.

Testing Codes for DFPlayer Mini MP3-TF-16P

To help you get started quickly with the DFPlayer Mini MP3-TF-16P, this section provides two fully working testing examples. First, you will find the Official DFRobot Library Example, which is ideal for beginners who want a simple and direct way to control the module. Then, you will see the Makuna Library Example, which is especially useful if your board uses the MH2024K16SS chip revision. Both examples have been verified and can be used immediately for wiring and functional tests.

1. Official DFRobot Library Example

To begin with, you can test the DFPlayer Mini MP3-TF-16P using the official DFRobot library. This example demonstrates basic commands such as initializing the module, playing tracks, adjusting the volume, and communicating over UART. Because it is straightforward and well-documented, it is perfect for first-time users.

2. Makuna Library Example (Supports MH2024K16SS Chip)

Alternatively, if your DFPlayer Mini module uses the MH2024K16SS chip, you may prefer the Makuna DFMiniMp3 library. This library provides smoother serial handling, better error reporting, and improved stability. Moreover, it is more robust in long-running applications, making it a great choice for advanced projects.

Setup Notes for DFPlayer Mini MP3-TF-16P

  • Format microSD as FAT16/FAT32
  • Name files using standard numeric format (e.g., 0001.mp3)
  • For ESP32/ESP8266 (3.3V logic), use a logic-level converter on RX/TX
  • Use a proper 8Ω speaker rated 1–3W
  • Avoid using noisy USB 5V power sources

Usage

  1. Install required libraries through Arduino Library Manager
  2. Select your board and port in Arduino IDE
  3. Upload the desired sketch
  4. Monitor serial output at 115200 baud (Makuna) or 9600 baud (Official)

Troubleshooting

  • Ensure correct wiring connections
  • Verify SD card is properly formatted (FAT32)
  • Check MP3 files are properly named and placed in mp3 folder
  • Monitor serial output for error messages
