The Nucleo F401 has 3 I2C master !
If you need to connect on one I2C master several I2C slave devices , with the same I2C id, you can use a extender like:
-PCF8575 I²C expander chip, http://www.sparkfun.com/commerce/product_info.php?products_id=8130
-PCF8574 (was sold by Futurlec )
There are several informations arduino + pcf8575

Accepted Answer

Thanks a lot Robert, But I need to connect sensors with every i2c master and I couldn't able to achieve high speed, i.e.. I have reached only about 200+ Hz, but I need atleast 350+ fused data. How can I change the MPU9150 library to support that
