Hello,
I want to connect multiple voltage sensors to the nucleo board. Lets say 4 voltage sensors of same kind with same address. So, I thought I could connect all the 4 sensors with the nucleo board with the help of I2C communication protocol.
Is this possible?
If possible I had a doubt that all the 4 voltage sensors will be having same addresses. But I want to call all the fours sensors at a time. How can I do this.
Please any help.

IOf you want to access 4 I2C devices with the same address and have the result at the same time, you need a device with 4 I2C busses. If you can cope with some delay, you can use a I2C-Bus Switch like PCA9543, eventual cascaded to allow to provide different addresses. You you use a part with selectable addresses (2 pins) to differentiate.

What part number sensor and Nucleo? Let's try and narrow this down a tad..
