Technical specifications

  • Supply voltage: 5 - 12V
  • Earn: 200x
  • Potentiometer of 10k for volume adjustment
  • LED indicating the power supply
  • Speaker cable jack
  • Distortion up to 0.2%


Instructions for use

1. Power up the audio amplifier.

The module is powered with a voltage between 5 V and 12 V. The supply pins are marked with VCC and GND. On the module are marked 2 pins with GND, but it does not matter which pin you connect the table.

2. Connect a speaker to the mode.

On the opposite side of the module, there are two screw terminals useful for connecting a speaker with a 8Ω impedance.

3. Connect an audio signal source.

The audio input is made through the pins marked with IN and GND. If the audio signal and the power supply come from a common source (for example: an Arduino development board), you need to connect a single mesh wire (GND).

Example of use with an Arduino development board

The module connects to the development board:

  • GND pin   of the mode connects to a GND  pin of the development board;
  • the  IN  pin connects to the digital pin 8;
  • the VCC  pin  of the module connects to the 5V pin of the development board
