Accurate and reliable
Zero-drift claim seems accurate based on my long-term tests. The data remains consistent over hours of operation. Great addition to any electronics workbench.

Essential for robotics power management
I use these on all my robot controllers now. Being able to monitor both voltage and current bidirectionally helps me understand motor load efficiently. Highly recommended.

Perfect for battery monitoring projects
This module works flawlessly with my Arduino setup. The I2C communication is stable, and the library support is excellent. Measuring current draw on my solar project has never been easier.

Great value, minor soldering needed
The sensor is accurate and easy to integrate. I had to solder my own headers, but that is expected for this price point. Readings match my multimeter very closely.

Good documentation support
Found plenty of examples online to get started quickly. The only reason for 4 stars is that the default address conflicted with another device, but changing it via jumpers was simple.

Compact and powerful
Small form factor fits perfectly in my enclosure. It handles the 24V system without breaking a sweat. Very happy with this purchase for my off-grid monitoring system.
Q: Is a library available for ESP32?
A: Absolutely. There are several open-source libraries compatible with ESP32, Arduino IDE, and PlatformIO that support the INA219 chip.
Q: Can this module measure negative current flow?
A: Yes, the INA219 supports bidirectional current monitoring, allowing it to measure both charging and discharging currents effectively.
Q: What is the maximum bus voltage this can handle?
A: The module is rated for bus voltages up to 26V. Please ensure your system stays within this limit to avoid damaging the sensor.
Q: How do I change the I2C address?
A: You can change the I2C address by soldering bridges to the A0 and A1 pads on the back of the module. Refer to the datasheet for the address table.
Q: Does this come with header pins pre-soldered?
A: No, this module is typically shipped without pre-soldered headers to allow flexibility for breadboard use or direct wire soldering depending on your project needs.
