They are here! New stock has arrived.
The new V1.1 has 2 changes:
green PCB, not blue
I removed the solder mask between the CH+/- solder points and sense resistors. This should result in solder flowing onto these tracks and therefore thicker tracks that can handle more current.
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.
