Ale jaki tutaj opis jest potrzebny? Bierzesz datasheet i wszystko wiesz.

"9.2 I2
C Interface
I2
C is a two-wire interface comprised of the signals serial data (SDA) and serial clock (SCL). In general, the
lines are open-drain and bi-directional. In a generalized I 2
C interface implementation, attached devices can
be a master or a slave. The master device puts the slave address on the bus, and the slave device with the
matching address acknowledges the master.
The MPU-60X0 always operates as a slave device when communicating to the system processor, which thus
acts as the master. SDA and SCL lines typically need pull-up resistors to VDD. The maximum bus speed is
400 kHz.
The slave address of the MPU-60X0 is b110100X which is 7 bits long. The LSB bit of the 7 bit address is
determined by the logic level on pin AD0. This allows two MPU-60X0s to be connected to the same I2
C bus.
When used in this configuration, the address of the one of the devices should be b1101000 (pin AD0 is logic
low) and the address of the other should be b1101001 (pin AD0 is logic high)."
Czyli na jednej lini IIC możesz mieć dwa układy, pod warunkiem, że ustawisz im różne adresy. Jak podłączyć coś po iic do raspberry to na yt jest dużo filmików. Podłącz najpierw jeden. Skomunikuj się, potem podłącz drugi itd.
