It offers programmable calibration for direct current and power readings, operates across a wide temperature range (-40°C to +85°C), and supports voltages from 3.0 to 5.5V. Compact and lightweight, it’s ideal for advanced monitoring in Arduino, Raspberry Pi, and other embedded systems. ## Description Features: The programmable calibration register reads the current directly in amps and reads the power in watts. Up to 128 samples can be averaged for filtering in noisy environments. The I2C interface has a timeout setting that not only avoids bus lock, but also provides a high-speed mode that meets communication requirements of up to 3.4 MHz. All features of the INA219 support software programmable. Single-supply operation with operating voltages from 3.0 to 5.5V.
