Good accuracy, easy to solder
Came with headers included which was nice. Accuracy seems spot on when compared to my multimeter. Only downside is the I2C address jumper pads are a bit small to work with.

Essential for solar monitoring
Using this to monitor my small solar panel output. It handles the fluctuating voltage well and the bidirectional feature lets me see when the battery is charging vs discharging.

Compact and lightweight
Ideal for drone telemetry where weight matters. Small footprint and provides all the data I need to prevent battery over-discharge during flights.

Great but needs calibration for precision
Works out of the box for general estimates. If you need high precision, you will need to calibrate the shunt resistor value in your code based on your specific unit.

Perfect for Arduino battery projects
This module works flawlessly with my Arduino Uno. The library support is excellent, and reading both voltage and current simultaneously is very smooth. Great value for the price.

Reliable and robust
I have deployed three of these in different prototypes over the last six months. None have failed, and the zero-drift claim seems accurate as readings remain stable over time.
Q: Is this compatible with Raspberry Pi?
A: Absolutely. Since it uses the standard I2C protocol, it is fully compatible with Raspberry Pi models that have GPIO headers enabled for I2C.
Q: Can this module measure negative current?
A: Yes, the INA219 is bidirectional, meaning it can measure current flowing in both directions, allowing you to detect charging and discharging states.
Q: Do I need to buy a separate shunt resistor?
A: No, this module comes pre-populated with a 0.1 Ohm shunt resistor suitable for measuring currents up to approximately 3.2A.
Q: How do I change the I2C address if I have multiple modules?
A: You can change the I2C address by soldering bridges on the A0 and A1 pads located on the back of the PCB. The datasheet provides the address mapping table.
Q: What is the maximum voltage this can handle without damage?
A: The module is rated for bus voltages up to 26V. Exceeding this limit may damage the sensor, so please ensure your application stays within this range.
