Looking at the ina219. It only has 4 selectable ID's. This means that my project can have max 4 modules connected.
Now my question...
Can it be possible to connect 4 modules to arduino ID 8 and another 4 modules on arduino ID 9 and 4 more on arduino ID 10. Then have all 3 arduino's communicate via I2C to a master arduino for processing?
I have searched somewhat on google but mostly found how to connected more devices. Never found if there could be a workaround for this limit.

So as you have been told there are 16 addresses this device can have. So you can have 16 devices on the one bus.

It is a typical beginners response to throw multiple Arduinos at a project when some pecieved limit is reached. This is almost always a mistake and causes more problems than it it is worth

Yes, I comprehended form the datasheet without deep study. It is a new I2C trick for me. :o
Note it is a trick that will only work on devices designed to do this. It is not universally applicable. This is to clear things up for any newbee reading this not you.
