User Manual

Overview

This breakout board may well be the last current sensing solution you every need to buy. Not only can it do the work of

two multimeters, but it can do it with amazing precision and flexibility. With it you can measure high or low side DC

current, the bus voltage, and have it automatically calculate the power. It can do so over impressive voltage, current,

and temperature ranges with better than 1% accuracy, all while delivering the data in an easy to use format over I2C.

Works great with any microcontroller that is CircuitPython or Arduino compatible as well as single board computers

such as the Raspberry Pi. It is compatible with 3V or 5V logic and can measure bus voltages up to +36VDC. Not for use

with AC voltages.

Choose your side

Most current-measuring devices operate with some notable constraints that limit what they can be used for. Many are

low-side only which can cause issues as the ground reference changes with current. Others like it's little sister the

INA219B avoid this by measuring on the high side but need to change their shunt resistor to measure different current

ranges. The INA260 avoids these limitations, and with it's integrated precision shut resistor it can be used to measure

as much as +36V at up to 15A Continuous on either the

high or low side

. Wow!
