How to connect more I2C devices using the same I2C port?

Hi everyone!

I'm trying to use 3 devices in the same I2C port but all of them use the same address. I'm thinking about use multiplexer but I have no idea which one and how implement it! Could someone give any clue?

I've searched about it but I've found only about I2C mux to use with non I2C devices (LEDs, buttons etc).

I use Arduino Uno and the compiler 1.5.5.

Thanks!!

Can't you just change the address of each one?

What devices are these?
If they have a chip enable you could use that to turn them on and off.

CrossRoads,
That's perfect! tks!

HugoPT,
I cant! the chip allows to do it but the board dont.

Grumpy_Mike,
Im using a GY80 board and I'm using its accelerometer and gyroscope.

I think the CrossRoads' solution is ideal to me. tks all! :slight_smile:
