DFPlayer Mini MP3 Module for Arduino
Original price was: 145.00 EGP.110.00 EGPCurrent price is: 110.00 EGP.
The DFPlayer Mini MP3 Module for Arduino plays MP3, WAV, and WMA audio files from a Micro SD card. It features UART control, a built-in 3W amplifier, stereo DAC outputs, and standalone button-control modes.
DFPlayer Mini MP3 Module for Arduino
The DFPlayer Mini MP3 Module for Arduino adds music, speech, alarms, and sound effects to embedded projects. It reads audio files from a Micro SD card and plays them without requiring complex audio-processing code.
The module communicates with Arduino, ESP32, and other controllers through a UART serial interface. In addition, it supports standalone operation through IO buttons or ADKEY controls.
A built-in 3W mono amplifier can drive a small speaker directly through the SPK1 and SPK2 outputs. Meanwhile, the DAC_L and DAC_R pins provide stereo audio for an external amplifier or compatible audio input.

- Smart-home audio notifications
- Educational Arduino projects
- Vehicle and navigation voice prompts
- Access-control systems
- Automatic advertising players
- Toys, exhibitions, and scale models
Important Usage Notes
Use a stable power supply, especially when driving a speaker directly. Furthermore, DFRobot recommends placing a 1kΩ resistor between a 5V Arduino TX pin and the module’s RX pin.
Do not remove or insert the memory card while the module has power. Also, file names and copying order may affect track numbering and playback order.
The USB data pins do not provide a direct USB connection for uploading files from a computer to the Micro SD card.
