BILL OF MATERIALS

The following materials are needed:

  • STM32 NUCLEO-F072RB

  • USB cable - 6" A/MiniB

  • Adafruit I2S MEMS Microphone Breakout

  • Adafruit I2S Stereo Decoder

  • Jumper Wires

In principle, any board from STM32 can be used for these exercises, as long as it is supported by CubeMX, System Workbench, and supports at least two I2S buses.
