Introduction

GY-169 is a simple current converter for current measuring up to 5A. It incorporates the INA169 chip delivered by Burr-Brown from Texas Instruments, which intensifies the voltage read by a little shunt and gives a voltage yield relative to the deliberate current. The 0.1 ohms, 2W resistor permits an exact current estimation up to 5A with a 1V proportion for every Ampere. You can just interface the module with the microcontroller to control or monitor the current of any device.

Gy-169/ INA169 Board Overview

The breakout board comprises a shunt resistor, the INA169 chip, and a load resistor. While shunt and load may seem to have two resistors, just one is inhabited on the board. Assuming you might want to change the values of the resistors, you can change them by putting different values of resistors in parallel.

Working of Module

As current goes from VIN+ through the shunt resistor to VIN-, it makes a voltage drop across the shunt. The operation amplifier within the INA169 chip estimates the difference between the VIN+ and VIN-voltages and provides results based on that. It amplifies the output through the inside transistor, which sources a current out of the INA169 chip. As that current goes through RL to the ground, it generated a voltage level at VOUT.
