user70576: Can I change the I2C address of a device (MPU9250) connected to ESP 32 using int pin. I understand that in arduino board if we connect the int pin to A0 the default I2C address of MPU 9250 changes from 0x68 to 0x69. Is something similar possible with ESP 32? Which Pin I should connect to?

user69592: You have only two choices with this device on an I2C bus.  As stated in the datasheet:

So it's either:

0b1101000
0b1101001

The AD0 pin selects which of these two addresses are used.
