I am wondering if there are any benefits of using MAX471 voltage/current sensor on Analog 0 on a Wemos D1 mini versus using a resistor 220k perhaps to measure a 3.7 Li-on battery. I don't need to measure current just voltage?
So far I am thinking a resistor is better because it takes up less space which is important to my project- the smaller the better.
This is the Max471 board I have: https://www.amazon.com/gp/product/B01N6 ... UTF8&psc=1
I ask because I don't have a 220k resistor on hand and am eager to finish my project. Or maybe I should go dismantle some old electronics in search of the resistor?
