Raspberry Pi 2 MINIMU 9 v3 Sensor limit

Hi, I am new here.
I have a question about the MINIMU 9 v3 and Raspberry Pi 2.
Can I read more than 2 MINIMU 9 V3 Sensors with the Raspberry Pi 2?
I am not familiar with I2C. But I want to learn I2C.

Hello, Olli.

There are only two addresses available for the sensors on the MinIMU, so you cannot read more than two on a single I2C line. To get access to more MinIMUs, you might consider getting something like this I2C multiplexer that Adafruit makes.

Hi Jon.
Thank you for the answer.
Is a I2C multiplexer the same as a I2C port expander?

No. An I2C multiplexer will allow you to switch between different I2C busses. A I2C port expander is a device that allows for a microcontroller to have access to additional I/O pins, and its interface is I2C.
