4. Setup
4.1 Power Supply Connection
The module can be powered in two ways:
- Non-rechargeable Battery: Connect a 4.5-5V power source. If using the provided battery case, insert 3 x AAA batteries (not included) into the battery box. Ensure the ON/OFF switch on the battery box is in the OFF position before inserting batteries.
- Rechargeable Lithium Battery: Connect a 3.7V rechargeable lithium battery to the designated terminals on the board.
4.2 Component Connections
Connect the speaker and the control button to the corresponding terminals on the sound module board. Refer to the diagram below for proper wiring.
5. Operating Instructions
5.1 Transferring Audio Files
- Connect the sound module to your computer using the provided Micro USB data cable.
- Your computer will recognize the module as a USB drive, similar to an MP3 player.
- Drag and drop any MP3 or WAV audio files into the module's internal 8M storage.
- Safely eject the USB drive from your computer before disconnecting the cable.
5.2 Playing Sound
- Ensure the module is powered on (if using the battery case, switch it to ON).
- Press the connected control button.
- The audio file(s) you transferred will play. Depending on the configured mode, the sound will play once and automatically stop when finished, or loop/cycle through files.
6. Mode Switching
The sound module's playback behavior can be customized by adjusting the 3.3K resistors on the board. The default mode is '000'. You can select different trigger modes (button or TTL trigger) by connecting or disconnecting specific soldering pads (A, B, C) with 3.3K resistors. '0' means without a 3.3K resistor, and '1' means with a 3.3K resistor.
Control Mode Notes:
- In the table, '0' means without 3.3K resistor, '1' means with 3.3K resistor.
- Power-ON-Play Mode: The module will enter Power-ON-Play mode if there is a short circuit between two pads of the button. This means it will play voice immediately when powered on.
7. Maintenance
- Keep the module and components dry and clean. Avoid exposure to moisture or extreme temperatures.
- When replacing AAA batteries in the battery case, ensure the power switch is OFF. Dispose of old batteries responsibly.
- Handle the circuit board with care to avoid damaging components or soldering points.
- If the module is not in use for an extended period, it is recommended to remove the batteries.
8. Troubleshooting
8.1 No Sound Output
- Check Power: Ensure batteries are correctly inserted and charged, or that the external power supply is providing the correct voltage (4.5-5V or 3.7V). Verify the ON/OFF switch on the battery case is in the ON position.
- Check Connections: Confirm that the speaker and button are securely connected to the module board as shown in Figure 4 and Figure 5.
- Volume: Adjust the volume using the volume adjuster on the board (refer to Figure 4).
- Audio Files: Ensure MP3/WAV files are properly transferred to the module's 8M memory and are not corrupted.
8.2 Module Not Recognized by Computer
- USB Cable: Try a different Micro USB cable.
- USB Port: Connect to a different USB port on your computer.
- Drivers: On some systems, you might need to ensure generic USB mass storage device drivers are installed.
- Restart: Restart your computer and try again.
9. User Tips
- This module is highly versatile for creative DIY projects. Consider integrating it into custom music boxes, musical greeting cards, photo frames, albums, or gift boxes for a personalized touch.
- It's an excellent component for crafting unique and memorable gifts for special occasions such as Mother's Day, Valentine's Day, or Christmas.
- Experiment with different audio files and playback modes to achieve desired effects for your projects.
10. Frequently Asked Questions (FAQ)
