1/25/2024 0 Comments Arduino nano pinout ina 219![]() ![]() ![]() The maximum voltage that can be measured is 26V. Yes, it can measure the power in both directions! If you want to measure other currents or smaller currents more precisely, check out the datasheet to change that resistor. The maximum current of the measurement is determined by the shunt resistor found on the plate which is 0.1ohm (± 3.2A). It has a jumper for making changes to the I2C address so you can connect more than one INA219 to a single microcontroller. ![]() Simply, connect wire serial through this device and it will give all the information provided via I2C communication. We are using the INA219 as a digital device that allows the measurement of current, voltage, and therefore power. Another Wattmeter project is here, but this time everything is controllable digitally. ![]()
