Thank you for the article. I am thinking of buying ESP8266 ESP12E (something like https://www.amazon.com/Temperature-Humidity-Atmosphetic-BH1750FVI-YellowBlue/dp/B07GPBBY7F). Once the development is over, can I power the board using a regular Smartphone 1A power adapter connecting to microusb port and run independent without connecting to computer in a room as a weather display monitor? If not, any suggestions on using a power supply to achieve the same.

Got info from internet search that one person is using smartphone 5v adapter. I believe the 3.3v ldo voltage regulator will take care of the task of converting 5v to 3.3 to board.
