Digital I2S Amplifier Breakout — MAX98357A 3W Class D
The Adafruit I2S 3W Class D Amplifier Breakout (MAX98357A) accepts digital I2S audio directly — no DAC needed. Feed it a digital audio stream from a Raspberry Pi, ESP32, or any I2S-capable board and it outputs up to 3W into a speaker. This makes it ideal for modern digital audio projects where you want to skip the analog stage entirely.
