• Connect the negative power supply (Ground) to any GND שפּילקע.
• זיכער מאַכן אַז די מאַכט צושטעל איז סטאַביל און אין די ספּעציפֿישע וואָלומעןtagע קייט צו פאַרמייַדן שעדיקן צו די מאָדול.

5.2. אַודיאָ אַרויסגאַנג פֿאַרבינדונג

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

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

5.3. אפציאנעלע פארבינדונגען

• 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. אַפּערייטינג ינסטרוקטיאָנס

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

6.1. פּאַוערינג אויף

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. בלועטאָאָטה פּערינג

1. Ensure the module is powered on and in pairing mode (indicated by flashing LED and/or voice prompt).
2. אויף אייער סמאַרטפאָון אָדער אַנדער בלוטוט-ענייבאַלד מיטל, נאַוויגירט צו די בלוטוט סעטטינגס.
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.

6.3. אַודיאָ פּלייַבאַקק

After successful pairing, you can play audio from your connected device. The audio will be transmitted wirelessly to the KCX BT003 module and output through the DAC_L and DAC_R pins to your connected ampליפיער / ספּיקערז.

6.4. Voice Prompts and LED Indicators

The module provides voice prompts for key actions (e.g., power on, pairing, connected). The LED indicator provides visual feedback on the module's status:

• שנעל פלאַשינג: Pairing mode, waiting for connection.
• Slow Flashing / Solid: קאָננעקטעד צו אַ בלועטאָאָטה מיטל.

7. וישאַלט

To ensure the longevity and optimal performance of your RIDEN KCX BT003 module, follow these maintenance guidelines:
