Usage

Getting Started

  1. Connect power supply — Connect a DC power supply (8V–26V, 3A minimum) to the board‘s power input terminals. Observe correct polarity; reverse polarity may damage the board despite built-in protection .

  2. Connect audio input — Connect your audio source (computer, phone, MP3 player, etc.) to the input terminals. Use a 3.5mm audio cable or stripped wires, ensuring left and right channels are correctly matched .

  3. Connect speakers — Connect speakers with 4–8Ω impedance to the output terminals. Match left and right channels correctly. Ensure speakers are rated for at least 30W to handle the amplifier’s output .

  4. Power on and test — Turn on the power supply and adjust the audio source volume. The board should begin operation immediately .

Important Notes

  • Heat dissipation — While the TPA3110 is highly efficient, ensure adequate ventilation for sustained high-power operation. A small heat sink may be beneficial in enclosed spaces .

  • Power supply quality — Use a stable, clean power supply to avoid noise and distortion in the audio output .

  • Input signal level — Ensure the audio input signal is within the acceptable range to prevent clipping and distortion.

Typical Applications

  • Portable Bluetooth speakers — Compact size and high efficiency suit battery-powered designs

  • DIY audio projects — Ideal for custom speaker builds and sound systems

  • Computer audio upgrades — Replace weak onboard audio with powerful amplification
