Description

Class-D mono audio amplifier module based on the MAX98357 chip. It can work with a 4 to 8 ohm speaker of up to 2.5 watts and communicates via I2S. It allows users to set different modes (off, left channel, right channel and mixed) by changing the resistance on the SD pin (the default is mixed mode). It can work with popular development boards including Raspberry Pi, ESP32 and STM32, which are equipped with I2S audio interface. Thanks to its small size, it will find application in building a small audio player. Full documentation and sample programs are available on the product page.
