Overview

The INA219EVM is an evaluation module for the Texas Instruments INA219 digital current shunt and power monitor. It provides an easy way to measure shunt voltage, bus voltage, current, and power over an I2C interface. The board includes the INA219 device with supporting components and ships with basic cabling to connect to a host MCU or development platform.

Why Choose This Part

The INA219EVM lets engineers evaluate the INA219 IC and its measurement accuracy without PCB or layout work, accelerating prototyping. Its I2C interface makes it easy to integrate with common platforms (Arduino, Raspberry Pi, or any I2C master) and existing firmware. Using the EVM avoids early mistakes in BOM and layout while providing reference routing and component choices.

Applications

Embedded power profiling
Measure real-time current and power consumption of microcontroller boards and modules during development and debugging.
Battery-powered device testing
Track battery draw, discharge behavior, and verify power budgets for portable systems.
Power rail monitoring
Monitor supply rails for overcurrent conditions and validate power-supply designs on prototype hardware.
Lab bench measurements
Quickly verify shunt resistor and current-sensing circuits without designing a custom PCB.

Getting Started

Connect the EVM to your MCU or SBC over I2C and supply the measurement shunt path as described in the TI user guide. Common quick-start platforms include Arduino and Raspberry Pi; community libraries such as the widely used Adafruit INA219 library can read current, bus voltage, and power. Consult the INA219 datasheet and the EVM user guide for register configuration, calibration, and shunt resistor sizing.
