MarkT:
That module doesn't bring out the 3 pairs of sense pins separately,it cannot be used as a high-side current sensor, only low-side. Ground is used as the return for all channels.
True.
Are you sure about that.
I see one side of all shunts connected to a common via.
And the other sides of the three shunts to individual vias.
No ground connection to the shunts.
This board can only be used for high-side sensing of three loads connected to a common supply.
Not even sure if the chip is bi-directional (like the INA219).
Couldn't find it in the datasheet, so I assume it's not.
