Тохиргоо
Зөв тохируулахын тулд эдгээр алхмуудыг дагана уу ampөргөх самбар:
- Микрофоныг холбоно уу: 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.
- Чанга яригчийг холбоно уу: 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).
- Эрчим хүчийг холбох: Connect a DC power supply (5V-12V) to the positive and negative terminals of the ampөргөгч самбар. WARNING: Do not reverse the polarity of the power supply, as this will damage the module.

Засвар үйлчилгээ
To ensure the longevity and optimal performance of your DKARDU Mini Microphone Amplifier Board, consider the following maintenance guidelines:
- Хуурай байлгах: Protect the module from moisture and liquids, as water can cause short circuits and damage components.
- Зөөлөн цэвэрлэх: If cleaning is necessary, use a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Болгоомжтой харьцах: The board contains delicate electronic components. Avoid dropping or subjecting it to strong impacts.
- Зөв хадгалалт: Ашиглаагүй үед модулийг сэрүүн, хуурай газар, нарны шууд тусгал болон хэт өндөр температураас хол хадгална уу.
Алдааг олж засварлах
Хэрэв танд асуудал тулгарвал amplifier board, refer to the following common problems and solutions:
- 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.
- Эрчим хүчний хангамжийн хэмжээг баталгаажуулна ууtage is within the 5V-12V range. Voltage below 5V will result in significantly reduced sound.
- Verify all connections are secure and correct according to the wiring diagram.
- 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.
- Оролтын хэмжээг баталгаажуулна ууtage нь 15 В-оос ихгүй байна.
