INA226 I2C Voltage Current and Power Monitor Module

The INA226 I2C Voltage Current and Power Monitor Module is a high-precision digital power monitoring solution based on the INA226 current-shunt and power monitor IC. It measures bus voltage, current and power and communicates the measurement data digitally through the I2C interface, making it easy to integrate with Arduino, ESP32, Raspberry Pi, STM32 and other microcontroller platforms. With 16-bit measurement resolution, programmable conversion settings and support for both high-side and low-side current sensing, the INA226 Voltage Current Power Monitor is suitable for applications where accurate electrical monitoring is required. The device can monitor bus voltages from 0V to 36V, while the module’s actual current measurement capability depends on the onboard shunt resistor and its configuration. The INA226 I2C Current Sensor Module supports bidirectional current measurement, allowing it to monitor both current flowing into and out of a load. This makes it particularly useful for battery charge/discharge monitoring, DC power supplies, solar systems, battery-powered equipment, robotics, IoT devices and energy monitoring projects.
