Part Name: INA219 High Side DC Current Sensor Breakout – $26V$ $\pm 3.2A$ Max

Part Description: The INA219 is a breakout board for a DC current sensor that can be used to measure the current passing through a given part of a circuit. The current sensor works by using a precision amplifier to measure the voltage across a current-sensing resistor, which can then be used to calculate the current. The analog current measurement is converted to a digital reading with its onboard 12-bit ADC and sent out via I2C communication to your desired interface. This current sensor can even be placed on the high side of a load to safely measure current up to $\pm 3.2A$.
