Adafruit INA260 High or Low Side Voltage, Current, Power Sensor

Introducing the INA260 High-Precision Current Sensor Breakout Board – a versatile and precise solution for all your current sensing needs. This breakout board can do the work of two multimeters, offering high or low-side DC current measurement, bus voltage monitoring, and automatic power calculation, all with incredible precision.

Key Features:

• Dual-Functionality: Measures high or low-side DC current, bus voltage, and calculates power—all in one device.
• Precision: Achieves better than 1% accuracy across a wide range of voltage, current, and temperature conditions.
• I2C Interface: Outputs data in an easy-to-use I2C format, making it simple to integrate with microcontrollers and single-board computers like Raspberry Pi.
• Wide Compatibility: Works with both 3V and 5V logic systems, perfect for any microcontroller that's CircuitPython or Arduino compatible.
• Voltage Range: Can measure bus voltages up to +36VDC (note: not suitable for AC voltages).

Impressive Capabilities:

• Current Range: Measures current up to 15A continuous with a 2 milliohm precision shunt resistor. It provides a resolution of 1.5mA with a 16-bit ADC.
• High & Low-Side Configurations: Unlike other sensors, the INA260 can be used in both high-side and low-side configurations without needing to change components.
• Shunt Resistor: The integrated 0.1% precision 2 milliohm shunt resistor allows for ultra-low voltage drop, which is so small that some multimeters may even register it as a short.
• Advanced Power Measurement: Retrieve bus voltage and power calculations accurately, especially in high-side configurations. For low-side measurements, some modifications are required.

Specifications:

• I2C Interface for easy communication with microcontrollers and SBCs.
• 0.1% Precision 2 milliohm integrated shunt resistor.
• 16-bit ADC for precise current measurements.
• Current Measurement: Up to 15A continuous.
• Voltage Measurement: Up to 36VDC.
• Resolution: 1.5mA current measurement resolution.

Easy Integration:

The board comes fully assembled with a 5.08mm terminal block and header for easy wiring. Some light soldering is required to attach the header.

With the INA260 Breakout Board, you’ll have all the tools you need to measure current, voltage, and power accurately and efficiently. It's the perfect addition to any project requiring precise current sensing over a wide range of conditions!
