I want to use Arduino Pro Mini 3.3V, here:
https://learn.sparkfun.com/tutorials/us ... o-mini-33v
it says:
"If you have a supply that’s greater than 3.3V (but less than 12V), you’ll want to connect that to the RAW pin on the Mini. This pin is akin to the VIN pin, or even the barrel jack, on the Arduino Uno. The voltage applied here is regulated to 3.3V before it gets to the processor."
So in order to achieve longer time duration on the circuit, it is better to use a 6V Sealed Lead Acid battery or a 3.7V Lipo?
