hello,
I have found this topic after spending two days on trying to understand that, and another - INA219 module. That is very interesting for me....
I have some additional equipment in car which I would like to monitor online - 24/7 - how many power they are consume over time. I need that connected 24/7 and I can't disconnect it from main power.
I would like to build any tool which allow me to monitor the current 3 different channels. I can agree on that, the voltage value of all of them will be shared, and will have same value.
But I would like to confirm - if that module - INA3221 - could usable in my case? I would like to get info like CH1 - 7A. CH2 - 1,5A, CH3 - 0,6A (only example values).
What current will be the highest possible to this board? That is not ultra-durable - one cable which supplies the whole board (POW&GND holes) I suppose?
And last, but not least - if that board will be better solution instead of 3xINA219?
As I wrote - the voltage value will be constant in my case - that this is not a problem here.
So, I would be very happy for your opinion about my problem - I can change my plans with that.
Thank you for any answers
have a great time !
