The following images illustrate the RIDEN KCX BT003 Bluetooth Audio Receiver Module from various angles, highlighting its components and pinout.

5. Postavljanje i ožičenje

Proper wiring is essential for the correct operation of the KCX BT003 module. Refer to Figure 4.4 for the pinout diagram. Always ensure power is disconnected before making any connections.

5.1. Priključak napajanja

• Connect the positive power supply (3.3V to 5.0V DC) to the VBAT pribadača.
• Connect the negative power supply (Ground) to any GND pribadača.
• Provjerite je li napajanje stabilno i unutar navedenog volumenatage range to prevent damage to the module.

5.2. Priključak audio izlaza

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

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

5.3. Dodatni priključci

• 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. Upute za rad

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

6.1. Uključivanje

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. Bluetooth uparivanje

1. Ensure the module is powered on and in pairing mode (indicated by flashing LED and/or voice prompt).
2. Na pametnom telefonu ili drugom uređaju s omogućenom Bluetooth vezom idite na postavke Bluetootha.
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. Reprodukcija zvuka

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 amplifier/zvučnici.

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:

• Brzo treptanje: Pairing mode, waiting for connection.
• Slow Flashing / Solid: Povezano s Bluetooth uređajem.

7. Održavanje

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

• Čuvati na suhom: Avoid exposing the module to moisture or liquids, as this can cause short circuits and damage.
• Nježno očistite: Ako je potrebno čišćenje, koristite meku, suhu krpu. Nemojte koristiti jake kemikalije ili abrazivne materijale.
• Rukovati pažljivo: This is a sensitive electronic component. Avoid dropping it or subjecting it to strong impacts.
• Statična struja: Take precautions against electrostatic discharge (ESD) when handling the module, as static can damage sensitive components.
• Ventilacija: Ensure adequate ventilation if the module is enclosed in a case, especially if other heat-generating components are present.

8. Rješavanje problema

If you encounter issues with your KCX BT003 module, refer to the following troubleshooting steps:

8.1. No Power / Module Not Responding

• Provjerite priključke napajanja: Verify that VBAT and GND are correctly connected and that the power supply is providing 3.3V-5.0V DC.
• Provjerite napajanje: Ensure the power supply itself is functional and providing sufficient current.

8.2. Cannot Pair with Bluetooth Device

• Module in Pairing Mode: Confirm the module is powered on and its LED is flashing rapidly, indicating it's in pairing mode.
• Bluetooth uređaja uključen: Ensure Bluetooth is enabled on your smartphone or audio source device.
• Udaljenost: Keep the module and your device within close proximity (e.g., 1 meter) during pairing.
• smetnje: Move away from other 2.4GHz wireless devices that might cause interference.
• Zaboravi uređaj: If previously paired, try forgetting the module from your device's Bluetooth list and re-pairing.

8.3. No Audio Output / Poor Audio Quality

• Check Audio Connections: Verify that DAC_L, DAC_R, and audio GND are correctly connected to your amplifier/zvučnici.
• Amplifier/Speaker Functionality: Osigurajte svoje amplifier and speakers are working correctly.
• Razine glasnoće: Check the volume settings on both your source device and your ampsredstvo za podsticanje.
• Udaljenost i prepreke: Ensure the Bluetooth connection is stable and within range (up to 10m). Walls or other obstacles can degrade signal quality.
• Izvorni zvuk: Test with different audio sources or files to rule out issues with the source material.
