The CJMCU-226 INA226 is a powerful voltage, current, and power monitoring module designed for high precision in both high-side and low-side sensing applications. With its bi-directional current sensing capability and wide operating range, this module is perfect for a variety of applications, including battery management systems, power supply monitoring, and energy management.
The INA226 communicates over the I2C interface and allows for configurable averaging and 12 programmable addresses, providing flexibility in complex systems. It features impressive accuracy, with a gain error of only 0.1% and a maximum offset of 10μV. Designed to operate from a 2.7V to 5.5V power supply, it can monitor bus voltages up to 36V, making it a versatile solution for monitoring and controlling power in your projects.
Features:
- Voltage Range: Monitors bus voltages from 0V to 36V
- Bi-Directional Current Sensing: Capable of measuring current in both directions
-

Jargon buster
Plain-language definitions for the technical terms used above.
- Gain error
- Gain error is a scaling error where the DAC output rises slightly too much or too little across its range. It matters for applications where the exact relationship between the digital value and output voltage is important.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
