Banggood

Little Great amplifier Board. Great Power and sound. A little noise at very low volume but in general ways an excellent amplifier. Package was great. It came in a cardboard box and plastic bag protection.

Used this board to build a Bluetooth speaker out of 4 inch pvc pipe. Powered it with a 5s 18650 battery pack. This board connects fast to Bluetooth and sounds great on the 4ohm 3.5 inch 30 watt rms speakers and tweeters I used. I will definitely use this again in future builds. The only issue is you have to make connections to the push buttons on the board so you can control the volume and other functions. See the 3 red push buttons in the picture.

everything is fine about product except HISS SOUND

excelente... muito rápido na entrega .. recomendo

Obrigado a toda equipe, produto chegou em perfeitas condições, bem embalado e com uma super agilidade de entrega, ainda nao realizei os teste de funcionalidade, mas desde ja agradeço.

menor que eu pensei que fosse mas é bom assim mesmo. vou testar daqui a pouco

value for money compact size powerful

sound quality is not the greatest, you can really hear the difference in 10%THD compared to another amplifier. I am making a small kitchen BT music system, which will be ok for that type of work.
