INA3221 Triple Channel I2C Current Sensor Module

The INA3221 is a high-precision, three-channel current and voltage monitoring IC designed for advanced power management applications. Unlike the INA219, this module can monitor three separate channels at the same time, making it perfect for multi-load systems.

It communicates via the I2C interface and supports both 3.3V and 5V systems, ensuring easy integration with ESP32, Arduino, Raspberry Pi, and other microcontrollers.

Each channel can measure bus voltage up to 26V and current using onboard shunt resistors. With its high accuracy and multi-channel capability, the INA3221 is widely used in battery management, solar systems, server monitoring, and embedded electronics.
