Kurulum Talimatları
1. Güç Bağlantısı
The board can be powered using one of two methods:
- Mikro USB Bağlantı Noktası: Connect a standard Micro USB cable to the board's Micro USB port and a 5V DC power source (e.g., USB charger, power bank).
- Akü Terminalleri: Connect a 3.7V to 5V DC battery to the BAT+ (positive) and BAT- (negative) solder pads. Ensure correct polarity to prevent damage.
Not: Do not connect both Micro USB and battery power simultaneously unless the battery charging circuit is designed for it. Typically, only one power source should be used at a time.
2. Ses Çıkışı Bağlantısı
Choose one of the following methods to connect your audio output device:
- 3.5 mm Ses Jakı: Plug your headphones or speakers directly into the 3.5mm stereo audio jack on the board.
- Solder Pads: Solder the Left (L), Right (R), and Ground (GND) wires of your speakers or amplifier to the corresponding solder pads on the board.
Kullanım Talimatları
1. Açma
Once power is supplied to the board (via Micro USB or battery), the LED indicator will illuminate, indicating the board is powered on and ready for operation.
2. Bluetooth Eşleştirme
- Ensure the Bluetooth decoder board is powered on. The LED indicator will typically blink, signifying it is in pairing mode.
- Akıllı telefonunuzda veya Bluetooth özellikli diğer cihazınızda Bluetooth ayarlarına gidin.
- Scan for available devices. The board should appear as a device named similar to "BT-MINI" or a generic Bluetooth audio device.
- Select the device to pair. Once successfully paired, the LED indicator on the board may change its blinking pattern or become solid.
- You may hear an audible confirmation tone from your connected speakers/headphones.
3. Ses Çalma
After successful pairing, any audio played on your connected Bluetooth device will be streamed to the decoder board and output through the connected speakers or headphones.
Bakım
- Tahtayı temiz ve tozdan arındırılmış halde tutun. Temizlik için yumuşak, kuru bir fırça veya basınçlı hava kullanın.
- Store the board in a dry environment, away from direct sunlight and extreme temperatures.
- Avoid physical shock or excessive vibration.
Sorun giderme
| Sorun | Olası Neden | Çözüm |
|---|---|---|
| Güç yok / LED kapalı | Incorrect power connection, insufficient voltage, faulty power source. | Check power supply (3.7-5V DC). Ensure Micro USB cable or battery connections are secure and correct polarity is observed. Try a different power source. |
| Cannot find Bluetooth device | Board not in pairing mode, device too far, interference. | Ensure the board is powered on and the LED is blinking (pairing mode). Move your Bluetooth device closer to the board. Restart both the board and your Bluetooth device. |
| Ses çıkışı yok | Incorrect audio connection, low volume on source device, faulty speakers/headphones. | Verify audio connections (3.5mm jack or solder pads). Check volume on your paired device. Test speakers/headphones with another audio source. Ensure Bluetooth is successfully paired. |
| Poor audio quality / intermittent connection | Distance from source, obstacles, interference. | Reduce distance between the board and the Bluetooth source device. Remove obstacles. Avoid strong electromagnetic interference sources. |
