සැලසුම
Follow these steps to correctly set up your amplifier board:
- මයික්රෆෝනය සම්බන්ධ කරන්න: 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.
- කථානායක සම්බන්ධ කරන්න: 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).
- සම්බන්ධක බලය: Connect a DC power supply (5V-12V) to the positive and negative terminals of the ampලයිෆයර් පුවරුව. WARNING: Do not reverse the polarity of the power supply, as this will damage the module.

නඩත්තු කිරීම
To ensure the longevity and optimal performance of your DKARDU Mini Microphone Amplifier Board, consider the following maintenance guidelines:
- වියළිව තබා ගන්න: Protect the module from moisture and liquids, as water can cause short circuits and damage components.
- මෘදු ලෙස පිරිසිදු කරන්න: If cleaning is necessary, use a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- පරිස්සමින් හැසිරවීම: The board contains delicate electronic components. Avoid dropping or subjecting it to strong impacts.
- නිසි ගබඩා කිරීම: When not in use, store the module in a cool, dry place, away from direct sunlight and extreme temperatures.
දෝෂගවේෂණය
ඔබට ගැටළු ඇති වුවහොත් ඔබේ 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.
- බල සැපයුම් පරිමාව සහතික කරන්නtage 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.
- ආදාන පරිමාව සහතික කරන්නtage 15V ට වැඩි නොවේ.
