⚡ Power your projects with precision and confidence!
The AITRIP 5 pcs CJMCU-219 INA219 sensor modules deliver high-precision bidirectional DC current and power monitoring with 1% maximum error accuracy. Designed for I2C interface compatibility, these compact SOT23 footprint modules operate reliably across a wide temperature range (-40°C to +85°C) and a working voltage of 3 to 5V, making them ideal for Arduino and Raspberry Pi projects requiring precise power measurement.

Doesn’t use the same chip in the pictures
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.

2 out of 5 DOA so far
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

Works great, accurate, repeatable
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
