I have this Hydrogen Sulfide gas sensor and the datasheet says the supply voltage requires a regulated voltage with a min of 2.6v and max of 3.6v
I can’t find any datasheet for the nodemcu v3 (spent hours looking, but none mention anything relevant) that’s says whether or not the power output of the 3.3 pin is regulated (how can I tell?) but others have said an Arduino Uno’s 5v and 3.3v pins are regulated. Assuming it is regulated (I know what they say about assumptions), are there any reasons why I should be concerned about using the 3.3 pin?
What about using the aforementioned Arduino Uno, whose power pins are regulated?
This sensor is kinda pricey and I don’t want to burn it out due to stupidity.
