  2. Audio Input: Connect your audio source (e.g., smartphone, MP3 player, microcontroller audio out) to the audio input pins. A coupling capacitor can be used in the input path to reduce noise.
  3. Speaker Output: Connect a speaker (typically 4Ω to 8Ω impedance) to the onboard speaker terminal block.
  4. Volume Adjustment: Use the onboard 10K potentiometer to adjust the audio output volume.
Application Scenarios
  • DIY Speaker Systems: Building custom bookshelf or portable mono speakers.
  • Embedded Audio Solutions: Integrating sound into projects using platforms like Arduino or Raspberry Pi.
  • Educational Kits: Ideal for students and hobbyists learning about audio amplification circuits.
  • Prototyping: Useful for quickly testing audio sections in new electronic product designs.
Q: Is this a stereo amplifier module?

No, this is a mono (single channel) amplifier module. You would need two of these modules to achieve stereo sound.

Q: Can I power this module with a 12V battery?

Yes, the module is designed to work efficiently with a 6V to 12V DC power supply, making a 12V battery a suitable option.

Q: What kind of speaker should I use with this module?

A speaker with an impedance of 4 ohms to 8 ohms is recommended for optimal performance.

Q: Does the module need a heatsink?

Yes, while some modules come with a small heatsink attached to the TDA2030A IC, proper heat management is crucial for reliable operation, especially at higher power outputs. The chip has a thermal shutdown system to prevent damage, but a sufficient heatsink is highly recommended.

Q: Can I use a dual (bipolar) power supply?

This specific module is configured for a single-supply DC input (6-12V). The TDA2030A chip itself can work with a dual power supply in a different circuit configuration, but this board is designed for a single source.

Q: How do I troubleshoot if there is no sound?

Check all wiring connections, especially power polarity and speaker connections. Ensure the audio input signal is present and the volume potentiometer is adjusted correctly. A humming sound when touching the input pin with a metal object (carefully) often indicates the amplifier IC is powered and functioning.
