Organizować coś
Follow these steps to correctly set up your amppłytka liifier:
- Podłącz mikrofon: 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.
- Podłącz głośnik: 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).
- Podłącz zasilanie: Connect a DC power supply (5V-12V) to the positive and negative terminals of the amplifier pokładzie. WARNING: Do not reverse the polarity of the power supply, as this will damage the module.

Instrukcja obsługi
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.
- Regulacja głośności: 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.
- Zgodność wejściowa: Ten amplifier is designed to work with electret, condenser, and moving coil microphones, as well as general audio signals.

Konserwacja
To ensure the longevity and optimal performance of your DKARDU Mini Microphone Amplifier Board, consider the following maintenance guidelines:
- Utrzymywać w suchości: Protect the module from moisture and liquids, as water can cause short circuits and damage components.
- Czyść delikatnie: If cleaning is necessary, use a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Zachowaj ostrożność: The board contains delicate electronic components. Avoid dropping or subjecting it to strong impacts.
- Prawidłowe przechowywanie: Gdy moduł nie jest używany, należy przechowywać go w chłodnym i suchym miejscu, z dala od bezpośredniego światła słonecznego i ekstremalnych temperatur.
Rozwiązywanie problemów
Jeśli napotkasz problemy z urządzeniem amppłyta główna, zapoznaj się z poniższymi typowymi problemami i rozwiązaniami:
- 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.
- Upewnij się, że napięcie zasilaniatage is within the 5V-12V range. Voltage below 5V will result in significantly reduced sound.
- Sprawdź, czy wszystkie połączenia są bezpieczne i prawidłowe, zgodnie ze schematem okablowania.
- 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.
- Upewnij się, że głośność wejściowatage nie przekracza 15V.
