Is ESP correctly works on (2.4-3) volts? As I see in specification, it says that we should power our ESPs with (3-3.6) volts... f
Tha data sheet really says 3V, but I have experimented with lower voltage and it worked.
I am not sure if 2.4V is save or even the limit but I have tested at this voltage. Probably the radio strength is degrading.
I have repeated the test.
I have tested with two NiMH batterys with a nominal 1.2V with a sum of (measured with DVM) somewhat below 2.5V. Here it still worked, the mail transmitted however says that the voltage measured from the ESP was 2.55V.
So it seems save for me to use a Limit of 2.6V in the software.
Still I do not know if this is typical and all modules work with this setting, you have to test ist individually as it is off the guaranteed specification.
