The stethoscope and blood pressure brick consists of a sound as well as pressure recorder. For sound the I2S (Inter-Integrated Circuit Sound) bus is used to communicate with the microcontroller. This interface allows streaming and recording audio to an audio codec board. The Everest Semiconductor ES8388 audio codec was chosen because its supported by Arduino Audio Tools library and Arduino Audio Driver and because Espressif created the Lyrat Audio modules with published reference designs.
