I2S 3W class D Amplifier Breakout Module - Max98357a

The AZ-Delivery DAC Amp Breakout works with the Raspberry Pi and makes the digital audio files ring. The standard I2S audio input not only decodes an analog signal, but is amplified and combined directly into a speaker, with 2 breakouts (I2S DAC + Amp).

Extensive application possibilities The 3W Amplifier allows excellent function with Arduino Zero, microcontroller or microcomputer with I2S audio outputs. 
Advanced Technology Built-in thermal and overcurrent protection make this amplifier very suitable for portable and battery-powered projects.

• Particularities
