The LED indicates the ON/OFF state and the battery voltage state. User can install this kit in a box easily and make their own audio amplifier product.

TSA2210 is a 2x8W class D audio amplifier board integrated with Bluetooth 4.0. It has perfect class-D architecture(based on TPA3110D2) and every channel has 8W power output. This board can be powered by any DC 8V-16V power supply. It can be used to drive any 4Ω or 8Ω passive speakers. The Bluetooth audio volume control circuit is also integrated on this board. Turning the knob in clockwise direction will increase volume, turning the knob in counterclockwise direction will decrease the volume. Clicking the knob will turn ON/OFF the amplifier.

It is perfect for your Hi-Fi application, the audio source can be cable input or Bluetooth. You may pair up the amplifier with a mobile phone or a computer that has Bluetooth function.
