The following images illustrate the RIDEN KCX BT003 Bluetooth Audio Receiver Module from various angles, highlighting its components and pinout.
5. Configuració i cablejat
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. Connexió a la font d'alimentació
- Connect the positive power supply (3.3V to 5.0V DC) to the VBAT pin.
- Connect the negative power supply (Ground) to any GND pin.
- Assegureu-vos que la font d'alimentació sigui estable i dins del volum especificattagrang e per evitar danys al mòdul.
5.2. Audio Output Connection
The module provides stereo audio output. These pins should be connected to an audio amplifier or directly to speakers if they have an integrated ampmés viu.
- 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. Connexions opcionals
- 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. Instruccions de funcionament
Once the module is correctly wired and powered, follow these steps to operate it:
6.1. Encès
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. Emparellament Bluetooth
- Ensure the module is powered on and in pairing mode (indicated by flashing LED and/or voice prompt).
- Al telèfon intel·ligent o a un altre dispositiu compatible amb Bluetooth, navegueu fins a la configuració de Bluetooth.
- Scan for available devices. The module should appear as "BT003" or a similar identifier.
- 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. Reproducció d'àudio
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/altaveus.
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:
- Parpelleig ràpid: Pairing mode, waiting for connection.
- Slow Flashing / Solid: Connectat a un dispositiu Bluetooth.
7. Manteniment
To ensure the longevity and optimal performance of your RIDEN KCX BT003 module, follow these maintenance guidelines:
- Mantenir sec: Eviteu exposar el mòdul a la humitat o a líquids, ja que això pot causar curtcircuits i danys.
