നിങ്ങളുടെ ഉപകരണം ശരിയായി സജ്ജീകരിക്കാൻ ഈ ഘട്ടങ്ങൾ പാലിക്കുക amplifier board:
- മൈക്രോഫോൺ ബന്ധിപ്പിക്കുക: 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.
- സ്പീക്കർ ബന്ധിപ്പിക്കുക: 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).
- പവർ ബന്ധിപ്പിക്കുക: Connect a DC power supply (5V-12V) to the positive and negative terminals of the ampലൈഫ് ബോർഡ്. WARNING: Do not reverse the polarity of the power supply, as this will damage the module.

നിങ്ങളുടെ ഉപകരണത്തിൽ പ്രശ്നങ്ങൾ നേരിടുകയാണെങ്കിൽ 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.
- വൈദ്യുതി വിതരണം വോളിയം ഉറപ്പാക്കുകtage 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.
