I need to use ESP-12S version in my future project. Datasheet says the power supply of ESP-12S is in range of 3.0V to 3.6V.
ESP-12S should be supplied with battery together with the rest of electronics. Can you guys recommend me some battery from your experience?
I intend to use ER14505M model. However, its nominal voltage is 3.6V which is the upper limit of ESP8266. Am I safe to power ESP-12S directly from that battery or it is better to use some kind of LDO 3.3V regulator?
Thanks in advance for your time and effort.
Sincerely,
Bojan.
