Audio amplifier module - MAX98357 - DFRobot DFR0954 perfectly works with microcontrollers with I2S audio outputs, such as ESP32 and can be used, for example, with IoT applications, Smart Home devices or Bluetooth audio players. The module is supplied with a voltage in the range of 3.3 V to 5 V and can generate more than 2.5 W of power. It is also possible to configure the sound reproduction method by changing the resistance on the SD lead.
