The Adafruit INA219 High Side DC Current Sensor Breakout Board enables precise power monitoring by measuring both the high-side voltage and DC current draw over I²C with ±1% precision. Utilizing the INA219B chip, it supports voltage measurements up to 26V and current measurements up to ±3.2A, with a 12-bit ADC providing a resolution of 0.8mA at full scale. The board features a 0.1Ω sense resistor, allowing for current measurements with minimal voltage drop. Equipped with a STEMMA QT / Qwiic connector, it facilitates easy integration into projects without soldering.
