The Adafruit INA219 module provides a complete solution for measuring current, voltage and power. It includes a 12-bit ADC that allows a current resolution of about 0.8 mA. The board has an internal 0.1 Ω shunt resistor and level shifting, so it can be used directly with 3.3 V and 5 V logic. Thanks to STEMMA QT connectors, the sensor can also be connected without soldering. An excellent choice for monitoring the current consumption of batteries, motors or other loads.
