I just bought an ESP32 and have no idea how I'm going to power it when I complete my project (my Arduino Uno has a power port that I connect to a 9v so I'm only familiar with that).
What are the best options for power? Could I connect 2 AA batteries to the 3v and ground?
Thanks
I power ESP32's in various ways.
Most common way is to get a 5V switching regulator.
ANother way is to buy a 5V xAmp wallwart, cut the connector and hook to the 5V and Gnd.
I am using solar to power 2 projects.
I have supplied 3.3V for lower power operations.
Just plug a 5volt cellphone charger with micro USB lead into the USB socket of the ESP32.
Or plug it into a cellphone powerbank.
Leo..
I'll try that, thanks!
