Notes:
1.The Interrupt pin from the audio codec can connect to any available Jetson Nano GPIO. If the
pin must be wake-capable, choose one of the GPIOs that supports this function.
2.I2C2 supports 1.8V operation since the interface is pulled to 1.8V through 4.7kΩ resistors on
the module. If another I2C interface on Jetson Nano is used, a level shifter will be required as
all the others are 3.3V.
