Nastavitev
Za pravilno nastavitev sledite tem korakom amprešilna plošča:
- Povežite 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.
- Povežite zvočnik: 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).
- Priključite napajanje: Connect a DC power supply (5V-12V) to the positive and negative terminals of the amplifier deska. WARNING: Do not reverse the polarity of the power supply, as this will damage the module.

Vzdrževanje
To ensure the longevity and optimal performance of your DKARDU Mini Microphone Amplifier Board, consider the following maintenance guidelines:
- Ohranjajte na suhem: Protect the module from moisture and liquids, as water can cause short circuits and damage components.
- Nežno očistite: If cleaning is necessary, use a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Ravnajte previdno: The board contains delicate electronic components. Avoid dropping or subjecting it to strong impacts.
- Pravilno shranjevanje: Ko modula ne uporabljate, ga shranjujte na hladnem in suhem mestu, stran od neposredne sončne svetlobe in ekstremnih temperatur.
Odpravljanje težav
Če naletite na težave s svojim ampploščo za reševanje, glejte naslednje pogoste težave in rešitve:
- 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.
- Prepričajte se, da je napajalnik 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.
- Zagotovite, da je vhodna voltage ne presega 15 V.
