MAX98367 I2S Amplifier Module

This is an I2S digital amplifier from DFRobot based on the MAX98357 I2S Class D amplifier module. The module works excellently with microcontrollers with I2S audio outputs such as the ESP32 and can be used in projects like IoT nodes, smart home devices, Bluetooth audio players, etc. The module supports a power supply of 3.3V-5V. And it can output over 2.5W power when operated from 5V and a 4Ω speaker. Additionally, the user can set different modes (off, left channel, right channel, and mixed) by changing the resistance at the SD port. The product is set to mixed mode by default.
