سیٹ اپ
Follow these steps to correctly set up your ampلائفائر بورڈ:
- مائیکروفون کو جوڑیں: 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.
- اسپیکر کو جوڑیں: 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).
- پاور سے رابطہ کریں: Connect a DC power supply (5V-12V) to the positive and negative terminals of the ampلائف بورڈ WARNING: Do not reverse the polarity of the power supply, as this will damage the module.

دیکھ بھال
To ensure the longevity and optimal performance of your DKARDU Mini Microphone Amplifier Board, consider the following maintenance guidelines:
- خشک رکھیں: Protect the module from moisture and liquids, as water can cause short circuits and damage components.
- آہستہ سے صاف کریں: If cleaning is necessary, use a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- دیکھ بھال کے ساتھ ہینڈل: The board contains delicate electronic components. Avoid dropping or subjecting it to strong impacts.
- مناسب ذخیرہ: When not in use, store the module in a cool, dry place, away from direct sunlight and extreme temperatures.
خرابی کا سراغ لگانا
اگر آپ کو اپنے ساتھ مسائل کا سامنا کرنا پڑتا ہے۔ 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.
- بجلی کی فراہمی والیوم کو یقینی بنائیںtage 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.
- ان پٹ والیوم کو یقینی بنائیںtage 15V سے زیادہ نہیں ہے۔
