The chip in the picture is the INA219b which is the high precision version of the chip. These modules chip with a bigger chip package compared to the ones in the picture and are not nearly as precise as the ones in the picture. If you don’t care about ~50mA accuracy then this should do.

I've used 2 out of 5 so far and none are replying to I2C. Really disappointed. I have an analog sensor I'll use instead

I've only used 3 out of the pack so far but they've all worked great. I've tried swapping them out and seeing if the readings were consistent and also compared them to a calibrated multimeter and they always seem spot on
