Review on MakerHawk MAX98357 I2S Audio Amplifier Module: Filtering Class D Amplifier for ESP32 & Raspberry Pi by Kathy Robinson
Adding I2S support to a microprocessor
Teensy 4.0 just came out and I was looking for a way to play some simple sounds. Previous versions of Teensy had a DAC (Digital to Analog Converter) in the system that I could hook up to the amps and speakers. Play pre-recorded sounds. Unfortunately, Teensy 4.0 does not have a DAC, but supports I2S. I was able to quickly add I2S support by connecting a MakerHawk MAX98357 to Teensy's I2S pins and to an Adafruit breadboard speaker. Well played.
- Suitable for microcontrollers or development board systems with I2S audio output, such as B. Raspberry Pi, Arduino and ESP32.
