I have purchased a INA3221 breakout board from eBay to replace several INA219s. They differ from the switchdoc INA3221 breakout board and the INA219 in having no V+ and V-. Instead they have three channels with CH1/2/3 and GND. I have tried to connect these pins as V+ and V-, but there is no current…
