Use suitable I2C pull-ups and logic levels for your controller. Enter the actual shunt resistance and the expected current range in your software calibration. The 36 V figure describes the sensor's measured bus range, not permission to power its logic pin from 36 V. Isolate power before rewiring; avoid exceeding the shunt's thermal rating.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWhat does the INA226 module measure?\u003c\/h3\u003e\u003cp\u003eIt reads DC bus voltage and voltage drop across a shunt, allowing calibrated current and power monitoring.\u003c\/p\u003e\n\u003ch3\u003eCan it measure current in both directions?\u003c\/h3\u003e\u003cp\u003eYes.
