INA219 Current Sensor Module

The INA219 based Current sensor module CJMCU-219 is an I2C interface based zero drift and bi-directional current/power monitoring module. It can sense shunt voltage, current, and power at the same time and submit the data via I2C protocol. It has 0.1 Ohms, a 1% shunt resistor to fulfill the requirement of current measurements. It has a powerful 12-bit ADC that converts the current sensed by a precision amplifier. The current sensing range is ±3.2A with a resolution of 0.8mA.

This module can measure DC voltage up to +26V.
