1. This device functions as two multimeters in one, delivering high accuracy and flexibility. It measures DC current on either the high side or low side, bus voltage, and automatically calculates power. Measurement accuracy exceeds 99% across a wide voltage, current, and temperature range, with data transmitted via I2C in an easy-to-use format. 2. Compatible with any CircuitPython or Arduino-compatible microcontroller, as well as single-board computers such as Raspberry Pi. Supports both 3V and 5V logic levels. Measures bus voltages up to +36 VDC. Not designed for AC voltage measurement. 3. The voltage drop across the integrated 2 mΩ (0.002 Ω), 0.1% precision shunt resistor is measured by an internal 16-bit ADC, enabling accurate current measurement across a wide range with 1.5 mA resolution. (The shunt resistance is so low that some multimeters may read it as a short circuit.) 4. In high-side configuration, bus voltage and power calculations are accurate and straightforward. For low-side bus voltage measurement, users must disconnect the jumper between V+ and VBUS and connect the VBUS pin directly to the voltage bus. Many current-sensing devices have notable limitations. Some operate only on the low side, which can introduce ground reference shifts during current flow. Others—like the INA219B—use high-side sensing but require changing the external shunt resistor to adjust current ranges. The INA260 overcomes these limitations: its integrated precision shunt enables continuous current measurement up to 15 A at +36 V, on either high-side or low-side configurations. Type: Current and Voltage Sensor Note: Slight variations in appearance, color, or packaging may occur between production batches.
