INA219 I2C Bidirectional Current Sensor Module

The INA219 is a bidirectional current/power monitoring control circuit, an I2C serial protocol-based current sensor module. The INA219 can read not only the changes across the shunt resistor but also the voltage values across it, allowing for power calculations.

This module comes with a 0.1 ohm 1% tolerance precision resistor. It can measure within a range of ±3.2A with this resistor, offering a resolution of 0.8mA at 12 bits.
