The ultimate digital monitor for precise power diagnostics.

When analog current sensors lack the resolution your project demands, the INA226 Current Sensor Module steps in. This high-precision, programmatic power monitor measures both shunt voltage drops and bus supply voltages up to 36V via an I2C interface, delivering 16-bit resolution for unmatched accuracy.

Unlike basic analog breakout boards, the INA226 features an on-chip multiplier that automatically calculates power in watts, offloading math from your microcontroller. It is highly configurable, featuring a programmable alert pin, adjustable conversion times, and built-in averaging to smooth out noise in volatile circuits.

Perfect For:

  • Precision Power Logging: Track the exact energy consumption of low-power microcontrollers, embedded nodes, or homelab hardware.

  • Battery Management & Harvesting: Monitor state-of-charge, charge controllers, and efficiency profiles for custom battery packs or solar/MPPT circuits.

  • Digital System Interfacing: Seamlessly chain multiple modules on a single I2C bus with microcontrollers like the ESP32, STM32, or Raspberry Pi.

Technical Specifications:

  • IC: Texas Instruments INA226

  • Interface: I2C (with multiple programmable addresses)

  • Bus Voltage Range: 0V to 36V

  • Maximum Shunt Offset Voltage: 10 µV (high accuracy, minimal error)

  • ADC Resolution: 16-bit

  • Calculated Outputs: Current (Amps), Voltage (Volts), and Power (Watts)

  • Sensing Configurations: Supports both High-Side and Low-Side sensing

  • Operating Voltage: 2.7V to 5.5V logic compatible
