INA219 I2C Bi-Directional Current Sensor Module

The INA219 I2C Bi-Directional Current Sensor Module is designed to solve all your power monitoring problems. Instead of using two multimeters, you can measure both current and voltage through I2C with 1% accuracy using a single board.

With this module, you can measure up to +26VDC using a 3V or 5V power supply. It allows you to estimate your battery life or calculate the efficiency of your solar panel.

With its precision amplifier circuit, it measures the voltage across a 0.1Ω resistor, providing 1% accurate measurements. The amplifier supports a maximum differential input of ±320mV, which enables current measurements up to ±3.2A. Thanks to the built-in 12-bit ADC, it can measure within the ±3.2A range with a resolution of 0.8mA.
