M5Stack INA226-10A Current Voltage Power Monitor Unit

M5Stack INA226-10A Current Voltage Power Monitor Unit is a fully isolated, high-precision measurement module designed for monitoring DC voltage (0–30V) and current up to 10A. It supports simultaneous acquisition of voltage and current data, making it ideal for high-load and power-sensitive applications. Key metrics—including current, voltage, and power—are accessible via the I2C communication interface, ensuring seamless integration with a wide range of host platforms.

The unit features an isolated power supply and I2C signal isolator, providing complete electrical separation between the measurement side and the control system. 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 automation scenarios.
