Product description: INA226-1A current, voltage and power sensor - Unit expansion module for M5Stack development modules
The M5Stack INA226-1A measurement module is an advanced voltage, current, and power monitoring device integrated with a high-precision 16-bit ADC. It supports voltages up to 30 V DC and currents in the ±1 A range, enabling the measurement of both positive and negative values. Thanks to the I2C interface and address 0x41, the module works with popular platforms such as Arduino and UiFlow2. Built-in galvanic isolation of signals and power ensures safe separation of the measurement path from the main control system, increasing interference immunity and safety. An automatic self-resetting fuse protects the device against overloads for added protection. Its compact design and integration-ready design make it ideal for industrial and educational applications.
