I currently have an INA3221 module from another supplier in use. However, this can apparently only measure three different currents. Only one voltage source is possible.

Now I ordered a Grove INA3221 from Amazon.com. Is it true that the voltage of three different and independent power sources can be measured?

How can you change the default address 0x40 - e.g. on 0x41?

Yes, three different voltages. Still needs a common ground, however!

You can change the i2c address according to the spec:
