This I2S digital amplifier based on the MAX98357 I2S Class D amplifier module works great with microcontrollers with I2S audio outputs like ESP32 and can be applied to projects like IoT nodes, smart home devices, Bluetooth audio players, and so on.

The module supports a 3.3V-5V power supply. And it can output over 2.5W of power when driven by 5V and a 4O speaker. Besides, it allows users to set different modes (off, left channel, right channel, and mixed) by changing the resistance on the SD port. The product defaults to mixed mode.

Featuring a small size, this I2S amplifier comes with stamp holes that enable it to be directly plugged into or mounted on a PCB and breadboard. Also, it is designed with PH2.0 and stamp holes for connecting speakers, flexible, and convenient to use.
