The ESP32-WROVER module supports I2S (Inter-IC Sound) communication, which is typically used for audio data transmission. The I2S peripheral allows the ESP32 to act as a transmitter (master or slave) or receiver of audio data.

The I2S pins can be assigned to almost any GPIO pin using the ESP32's flexible pin mapping, but the default pins are often used for convenience.

The default I2S pins for ESP32-WROVER are typically:

Signal	Default GPIO
I2S_WS (word select, also known as LRCK)	GPIO25
I2S_BCK (bit clock)	GPIO26
I2S_SD_OUT (serial data out, TX)	GPIO22
I2S_SD_IN (serial data in, RX)	GPIO35
