Product Description

Add high-quality audio playback to your electronics with the MP3-TF-16P MP3 Player Module. This ultra-compact, powerful module is designed to decode MP3 and WAV files directly from a MicroSD card. At Robogears, we recommend the MP3-TF-16P for its extreme versatility; it can be controlled via a simple Serial Port (UART) using an Arduino or operated as a standalone player using push-buttons (AD Key mode). With an integrated 3W amplifier, it can drive a small speaker directly, making it the perfect choice for adding voice alerts to security systems, background music to 3D-printed models, or sound effects to your Pimpri workshop's latest robotic creation.

Detailed Key Features

  • Built-in 3W Mono Amplifier: Allows for direct connection to a 4-8 Ohm speaker without needing an external audio power stage.

  • Full Serial Control: Supports standard UART commands to play specific tracks, adjust volume (30 levels), and change EQ settings (6 modes) via code.

  • Dual Output Modes: Provides both an amplified mono output and a high-fidelity stereo DAC output for connecting to headphones or external power amplifiers.

  • Standalone "AD Key" Support: Can be used without a microcontroller by connecting simple resistors and buttons to the ADK pins for Play/Pause and Track Skip.

  • Robust File Management: Automatically handles up to 100 folders, with each folder supporting up to 255 audio tracks.

All Technical Details

  • Pin Definition:

    • VCC/GND: Power Input (5V is most stable).

    • RX/TX: Serial Data (Connect to Microcontroller).

    • SPK1/SPK2: Direct Speaker Output (Mono).

    • DAC_R/DAC_L: Stereo Audio Output (Line Level).

    • BUSY: Status Indicator (Low when playing).

  • SNR Support: 85dB Dynamic Range for clear, crisp sound reproduction.

  • Applications: Navigation voice prompts, vending machine audio, lift floor announcements, and interactive DIY toys.

Prototyping & Engineering Tips (Robogears Exclusive)

  • The 1K Resistor Rule: At our Pimpri facility, we always remind makers to place a 1K ohm resistor in series with the RX pin when connecting to a 5V Arduino. This prevents electrical noise and "pops" during playback and protects the module's 3.3V logic.

  • SD Card Formatting: Ensure your MicroSD card is formatted to FAT32. For the most reliable playback, name your folders "01", "02", etc., and your files "001.mp3", "002.mp3".

  • Power Isolation: The module can draw significant current when driving a speaker at full volume. If your Arduino resets when the music starts, power the MP3-TF-16P from a dedicated 5V source rather than the Arduino's 5V pin.

  • Speaker Choice: For the best sound without distortion, use a 3W 8-Ohm speaker. Using a 4-Ohm speaker at max volume may cause the module to overheat or the sound to clip.

Package Includes

  • 1 x MP3-TF-16P MP3 Player Module
