      Description
      The amp is stereo efficient, digital amplifier power stage for driving speakers up to 2x30W/8Ω. The high efficiency of the amp allows it to do 2x30W/8Ω without external heat sink. This module has standby and mute function, so Arduino can control it how and when it works.

      Features:

      • Volume control
      • Audio output (L/R)
      • Audio input
      • Mute interface
      • 3.5 earphone input
      • Power supply

      Specification:

      • SNR      90(db) 
      • DR       0.01% 
      • Input impedance@ Voltage    3Ω@6V-19V    8Ω@6V-24V         
      • size       60mm*55mm*15mm
      • 25W + 25W continuous output power at THD = 10% with RL = 8 Ω and VCC = 26 V
      • Wide-range single-supply operation (4.5 - 26 V)
      • High efficiency (η = 90%)
      • Four selectable, fixed gain settings of nominally 20dB, 26dB, 32dB, and 36dB
      • Differential inputs minimize common-mode noise
      • Standby and mute features
      • Short-circuit protection
      • Thermal overload protection
      • Externally synchronizable
      • ECOPACK®, environmentally-friendly package

      how can I control the audio volume level with the Arduino (not only mute option...) ?

      Hello, you need a analog signal to control the volume, so a DAC module needed. I am sorry that we don't have one at Bazaar. I find one at Adafruit: https://www.adafruit.com/product/935Thanks.
