Sąranka
Follow these steps to correctly set up your ampgelbėjimo lenta:
- Prijunkite mikrofoną: Use a shielded cable to connect the electret microphone to the 'IN' and 'GND' terminals of the amplifier board. Pay close attention to the polarity of the electret microphone; incorrect polarity will result in very low or no sound.
- Prijunkite garsiakalbį: Connect your speaker to the 'OUT' terminals of the amplifier board. Ensure the speaker is positioned away from the microphone to prevent self-excited noise (feedback).
- Prijunkite maitinimą: Connect a DC power supply (5V-12V) to the positive and negative terminals of the ampkėlimo lenta. WARNING: Do not reverse the polarity of the power supply, as this will damage the module.

Priežiūra
To ensure the longevity and optimal performance of your DKARDU Mini Microphone Amplifier Board, consider the following maintenance guidelines:
- Laikyti sausai: Protect the module from moisture and liquids, as water can cause short circuits and damage components.
- Švelniai valykite: If cleaning is necessary, use a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Elkitės atsargiai: The board contains delicate electronic components. Avoid dropping or subjecting it to strong impacts.
- Tinkamas saugojimas: When not in use, store the module in a cool, dry place, away from direct sunlight and extreme temperatures.
Trikčių šalinimas
Jei kyla problemų dėl jūsų ampgelbėjimo plokštės atveju žr. šias dažniausiai pasitaikančias problemas ir sprendimus:
- Very Little or No Sound:
- Check the polarity of the electret microphone connection to the 'IN' and 'GND' terminals. Reversing the polarity will significantly reduce or eliminate sound.
- Užtikrinkite maitinimo šaltinio ttage is within the 5V-12V range. Voltage below 5V will result in significantly reduced sound.
- Patikrinkite, ar visos jungtys yra tvirtos ir teisingos pagal laidų schemą.
- Self-Excited Noise (Feedback):
- Ensure the speaker is positioned sufficiently far away from the microphone to prevent audio feedback.
- Check for proper shielding of the microphone cable.
- Module Not Functioning / Damaged:
- Verify that the DC power supply polarity is correct. Reversing the positive and negative connections will burn out the module.
- Įsitikinkite, kad įvesties ttage neviršija 15V.
