INA219 - I2C DC Current Sensor Module

The INA219 I2C DC Current Sensor Module helps you monitor DC current in microcontroller-based electronics projects. Its compact breakout board includes a shunt resistor, screw-terminal connection and labelled interface pins for straightforward wiring.

Features and connections

• INA219-based DC current monitoring board with an I2C interface.
• Labelled VCC, GND, SCL, SDA, VIN+ and VIN- connections.
• Onboard R100 shunt resistor and I2C address selection pads.
• Four mounting holes for integration into projects.
• Board markings specify a 0–26V bus range, 3.2A maximum current and 3–5V logic supply.

Project applications

Use it for DC load monitoring, battery-powered prototypes and electronics experiments with Arduino or ESP32 using suitable I2C software and wiring. Match the supply and I2C pull-up voltage to your controller. Confirm operating limits before connecting a load; do not connect directly to AC mains.
