M5Stack INA226-1A Current Voltage Power Monitor Unit

M5Stack INA226-1A Current Voltage Power Monitor Unit is a fully isolated, high-precision measurement module designed for monitoring DC voltage (0–30V) and current up to 1A. It supports simultaneous voltage and current acquisition, making it ideal for power-sensitive applications. Key parameters—including current, voltage, and power—can be accessed via the I2C communication interface, ensuring compatibility with a wide range of main control platforms.

The unit integrates an isolated power supply and I2C signal isolator, providing complete electrical separation between the measurement side and the host controller. A built-in self-resetting fuse automatically disconnects the circuit when current exceeds safe limits, enhancing equipment protection, personnel safety, and system noise immunity. This makes it well-suited for use in power management, battery monitoring, and industrial safety systems.
