7Semi INA260 High Precision I2C Current Voltage and Power Monitor Module with Integrated 2mΩ Shunt, 15A, 36V

The 7Semi INA260 Power Monitor Module is a compact, high-accuracy digital current, voltage, and power measurement board designed for embedded systems, IoT devices, battery monitoring, DC power analysis, robotics, industrial control, solar power monitoring, power supply testing, and energy management applications. Built around the Texas Instruments INA260, it provides direct digital readings over I2C without requiring an external shunt resistor.

This module integrates a precision 2mΩ current-sense resistor inside the INA260, helping reduce calibration errors, PCB layout issues, and external component count. It can measure bus voltages from 0V to 36V and supports bidirectional high-side or low-side current sensing, making it suitable for monitoring loads, batteries, chargers, DC motors, embedded boards, communication equipment, and power distribution systems.

With I2C/SMBus communication, programmable alert output, configurable averaging, and 4 programmable I2C addresses, the 7Semi INA260 module is ideal for Arduino, ESP32, STM32, Raspberry Pi, and other microcontroller-based projects that require reliable real-time current sensing, voltage monitoring, power logging, over-current detection, and system power optimization. The board operating temperature rating is -40°C to +80°C.
