Reliable and robust
We have bought ten of these for our makerspace. They have survived multiple student wiring errors and still function correctly. Very durable little board.

Great for solar charge controller logging
Logging data from my small solar setup. The I2C interface saves GPIO pins on my ESP32. It handles the voltage range perfectly without any issues.

Essential for motor control
I use this to monitor current draw on my DC motors. The bidirectional capability is crucial for my regenerative braking tests. Highly recommended for robotics applications.

Good accuracy, easy to wire
Setup was straightforward using the standard Adafruit library. The readings are consistent with my multimeter. Only giving 4 stars because the solder pads are a bit small for beginners.

Perfect for battery monitoring 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.
Q: Can this module measure negative current?
A: Yes, the INA219 supports bidirectional current measurement, allowing it to detect both charging and discharging currents effectively.
Q: How do I change the I2C address?
A: You can change the address by soldering bridges on the designated pads on the back of the PCB. The default is 0x40, with three other options available.
Q: Is a library available for Python on Raspberry Pi?
A: Yes, there are several open-source Python libraries available, including the popular CircuitPython and smbus2 implementations.
Q: What is the maximum voltage this sensor can handle?
A: The module can measure bus voltages up to 26V DC. Exceeding this limit may damage the chip.
Q: Does this come with header pins pre-soldered?
A: No, the module is typically shipped without headers to allow for flexible mounting options. You will need to solder your own headers or wires.
