• Connect the negative power supply (Ground) to any GND pin.
• Pastikan bekalan kuasa stabil dan dalam vol yang ditentukantagjulat e untuk mengelakkan kerosakan pada modul.

5.2. Sambungan Output Audio

The module provides stereo audio output. These pins should be connected to an audio amplifier or directly to speakers if they have an integrated amplebih hidup.

• Connect the left audio channel output to the DAC_L pin.
• Connect the right audio channel output to the DAC_R pin.
• Connect the audio ground to a GND pin.

5.3. Sambungan Pilihan

• LED: Connect an LED (with a current-limiting resistor) to this pin to indicate Bluetooth status (e.g., pairing, connected).
• MIC: If microphone input is desired, connect a suitable microphone to this pin and a GND pin.
• USB_DP / USB_DM: These pins are typically used for USB data communication or power, depending on the specific application and firmware. Consult advanced documentation if USB functionality is required.
• SD_DAT / SD_CMD / SD_CLK / ACKEY: These pins are for SD card interface, allowing the module to play audio directly from an SD card. Specific wiring and control logic are required for this functionality.

6. Arahan Operasi

Once the module is correctly wired and powered, follow these steps to operate it:

6.1. Menghidupkan

Apply power to the VBAT and GND pins. The module will typically emit a voice prompt indicating it is powered on and ready for pairing. If an LED is connected, it will likely flash to indicate pairing mode.

6.2. Berpasangan Bluetooth

1. Ensure the module is powered on and in pairing mode (indicated by flashing LED and/or voice prompt).
2. Pada telefon pintar anda atau peranti berdaya Bluetooth lain, navigasi ke tetapan Bluetooth.
3. Scan for available devices. The module should appear as "BT003" or a similar identifier.
4. Select the module to initiate pairing. A voice prompt will confirm successful pairing, and the LED will typically change to a solid state or a slower flash.
