You asked for it and here it is! A version of my improved INA3221 breakout board with no sense resistors populated. You can solder on your own sense resistors with the value you want, or you can use external (high current) shunts.
See documentation link below for more details on this board.
The commonly available INA3221 breakout board has a design flaw where all 3 channels use the same power supply. I wanted to fix that and make an improved version available.
My version implements the example circuit from the INA3221 datasheet and therefore allows 3 different power supplies; one per channel.
