Adafruit INA260 Current + Voltage + Power Sensor Breakout<\/div>
https:\/\/learn.adafruit.com\/adafruit-ina260-current-voltage-power-sensor-breakout\/python-circuitpython<\/div>
This breakout board may well be the last current sensing solution you every need to buy. Not only can it do the work of two multimeters, but it can do it with amazing precision and flexibility. With it you can measure the DC current and high or low side voltage, in addition to having it automatically calculate the power and do so over impressive voltage, current, and temperature ranges with better than 1% accuracy, all while delivering the data in an easy to use format over I2C.<\/div><\/div>
