The SOT23 INA219 Bi-directional DC Current Power Supply Sensor Breakout Module is an electronic module designed to measure both current and voltage in a bi-directional manner, allowing it to monitor power usage or supply in a circuit. It is based on the INA219 current sensor IC and is commonly used for various applications, including energy monitoring and management.

Key Features ofhe SOT23 INA219 module:

Current and Voltage Measurement: The primary function of the module is to measure both DC current and voltage simultaneously. It can measure current flowing in both directions (bi-directional) and provides voltage measurements.

INA219 IC: The module is built around the INA219, which is a high-side current shunt and power monitor IC. It includes a precision amplifier, an ADC (Analog-to-Digital Converter), and an I2C interface for communication.

High Accuracy: The INA219 IC is known for its high accuracy in current and voltage measurements, making it suitable for applications where precise power monitoring is required.

Configurable Range: Depending on the specific model and configuration, the module may offer adjustable current and voltage measurement ranges, allowing you to tailor it to your specific application.

I2C Communication: The module communicates with a microcontroller or other digital devices via the I2C (Inter-Integrated Circuit) protocol, making it easy to interface with various platforms.

Voltage and Current Outputs: The module typically provides both voltage and current outputs in a digital format that can be read by a microcontroller or computer. This enables real-time monitoring and logging of power data.

Onboard Shunt Resistor: The module includes an onboard shunt resistor, which is used for current sensing. The value of the shunt resistor determines the current measurement range.
