4. Setup Instructions
- Speaker Connection: Choose appropriate speakers and connect them to the module's audio output terminals (R, GND, L) as indicated in the wiring diagram (refer to Figure 2 for pad locations).
- Power Supply: Connect a DC 5V power supply to the input terminal. The LED indicator on the module will flash, signifying that the module has entered pairing mode. A prompt voice will confirm it is waiting for pairing.
- U-disk as Audio Source: If using a U-disk as an audio source, ensure it is formatted to FAT32 and has a maximum memory of 32GB. The module requires an external work voltage input from the two power supply pads when a U-disk is connected.
- Battery Connection (Optional): The module can charge a 3.7V/4.2V lithium battery. Connect the battery to the "BAT" pads. Note that the module does not provide charging or discharging protection functions for the battery. The micro USB port can also be used to supply power if a rechargeable lithium battery is connected to the "BAT" pads.
5. Operating Instructions
5.1 Bluetooth Pairing
- Ensure the module is powered on and in pairing mode (LED flashing).
- On your mobile phone or Bluetooth-enabled device, turn on Bluetooth.
- Search for Bluetooth devices and select 'XY-ABT' from the list.
- Once connected, the LED indicator will remain steadily ON, and a prompt voice will confirm successful connection. The module is now ready for audio playback.
5.2 Audio Playback
- After successful pairing, select music on your phone or connected device. The module will begin playing the audio.
- During playback, the LED indicator will slowly blink.
- Use the physical button on the module to play or pause the audio.
5.3 APP Control (Sinilink)
- Download and install the Sinilink APP on your smartphone.
- Open the Sinilink APP and register an account if you haven't already.
- In the APP, navigate to the connection section (often indicated by a dot icon on the right).
- Select 'Con Blu Dev' and initiate a Bluetooth search.
- Choose 'Sinilink-APP' from the discovered devices to connect to the module.
- Once connected via the APP, you can adjust volume, select next/previous tracks, play/pause, and select equalizer (EQ) presets.
- If the module disconnects, it will speak a prompt voice.
6. Maintenance
- Keep the module in a dry environment and avoid exposure to moisture or extreme temperatures.
- Clean the module gently with a dry, soft cloth. Do not use liquids or abrasive cleaners.
- Ensure proper ventilation if enclosed in a casing to prevent overheating.
7. Troubleshooting
- Signal Interference: Position the power amplifier board as far away as possible from Wi-Fi signals (e.g., routers) to avoid interference.
- No Audio Output: This module is a music decoder. It requires connection to an external amplifier, which then connects to speakers, to produce audible sound.
- Poor Audio Quality/Interference: Avoid using excessively long wires for connections, as this can introduce signal interference.
- U-disk Not Recognized: Ensure your U-disk is formatted to FAT32 and its memory capacity does not exceed 32GB.
- Battery Charging Issues: The module can charge 3.7V/4.2V lithium batteries but does not include charging or discharging protection. Use external protection circuits if necessary.
- U-disk Power Requirement: When using a U-disk as an audio source, ensure the module receives its work voltage from the two dedicated power supply pads, not solely via the micro USB if a battery is also connected.
- General Operation: Always refer to this manual and product description before use for optimal performance.
8. User Tips
