1. This device functions as two multimeters in one, delivering exceptional accuracy and flexibility. It measures high-side or low-side DC current, bus voltage, and automatically calculates power. Accuracy exceeds 99% across a wide voltage, current, and temperature range, with data output via I2C in an easy-to-use format. 2. Fully compatible with CircuitPython and Arduino-compatible microcontrollers, as well as single-board computers such as Raspberry Pi. Supports both 3V and 5V logic levels and measures bus voltages up to +36 VDC. Not designed for AC voltage measurement. 3. The voltage across the integrated 2 mΩ (0.002 Ω), 0.1% tolerance shunt resistor is measured by an internal 16-bit ADC, enabling precise current measurement with 1.5 mA resolution. (The shunt resistance is so low that some multimeters may indicate a short circuit.) 4. In high-side configuration, bus voltage measurement and power calculation 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 significant limitations—some only support low-side sensing, which can cause grounding issues when current flow alters the ground reference. Others, like the INA219B, use high-side sensing but require manual shunt resistor changes to adjust current ranges. The INA260 eliminates these constraints: its integrated precision shunt resistor enables continuous high-side or low-side current measurement up to 15 A at +36 V.
