Overview

Product Overview

INA219 I2C bi-directional current and power monitoring sensor module lets you monitor how much current a load is using and track power consumption in battery-powered or DC projects, with support for current flowing in either direction for charging and discharging applications. Built around the INA219, this I2C power monitor is ideal for Arduino, Raspberry Pi, ESP32, and other microcontroller or SBC platforms that need real-time energy data for robotics, solar systems, USB devices, home automation, and prototyping. It is a practical choice for battery packs, chargers, power banks, and electronics testing where current sensing matters. Use it to log load behavior or spot abnormal power draw during development.

Questions & answers

Frequently asked questions

Yes. It is an I2C current and power monitoring module suitable for Raspberry Pi, Arduino, ESP32, and similar microcontroller or SBC platforms that can communicate over I2C and support an INA219 software library.
Yes. ShillehTek supplies this module with the header already soldered, so it can connect to breadboards or jumper wires without soldering. You still need to wire the sensor correctly and install compatible INA219 code or libraries.
The module communicates over I2C using SDA and SCL, along with power and ground connections. Current is measured through the sensor’s shunt path, so the load must be wired through the monitoring terminals rather than only to the controller.
Yes. The INA219 supports bi-directional current sensing, making it useful for battery packs, chargers, solar projects, and power banks where current may flow during both charging and discharging.
A zero-current reading usually means the load current is not passing through the module’s shunt path, the I2C wiring is incorrect, or the software calibration is not set for the circuit. Verify the load wiring before replacing the sensor.
