1 Overview

The INA230 is a high-side current sensor and power monitor with an I2C interface. The INA230 monitors both current and supply voltage, with programmable conversion times and averaging modes. The INA230EVM is a platform used to evaluate the performance of the INA230 under various signal, shunt, and supply conditions.

This document gives a general overview of the INA230EVM and provides a general description of the features and functions to consider when using this evaluation module.
