Oppsett
Follow these steps to correctly set up your amplifier board:
- Koble til mikrofonen: 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.
- Koble til høyttaleren: 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).
- Koble til strøm: Connect a DC power supply (5V-12V) to the positive and negative terminals of the amplifier bord. WARNING: Do not reverse the polarity of the power supply, as this will damage the module.

Bruksanvisning
Once properly set up, the amplifier board will begin to amplify the audio signal from the connected microphone. The module supports various microphone types and can be integrated into different audio systems.
- Volumjustering: The board features a small potentiometer (labeled 'VOL') for adjusting the output volume. Use a small screwdriver or appropriate tool to carefully turn the potentiometer to achieve the desired volume level.
- Inndatakompatibilitet: De amplifier is designed to work with electret, condenser, and moving coil microphones, as well as general audio signals.

Vedlikehold
To ensure the longevity and optimal performance of your DKARDU Mini Microphone Amplifier Board, consider the following maintenance guidelines:
- Hold tørr: Protect the module from moisture and liquids, as water can cause short circuits and damage components.
- Rengjør forsiktig: If cleaning is necessary, use a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Håndteres med forsiktighet: The board contains delicate electronic components. Avoid dropping or subjecting it to strong impacts.
- Riktig oppbevaring: Når modulen ikke er i bruk, oppbevar den på et kjølig og tørt sted, unna direkte sollys og ekstreme temperaturer.
Feilsøking
Hvis du støter på problemer med din 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.
- Sørg for at strømforsyningen voltage 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.
- Sørg for at inngangsvoltage ikke overstiger 15V.
