Power Esp-01 from usb cable with wall adapter
Posted: Wed Dec 30, 2015 12:32 pmHello. I am interested in powering the esp-01, in a custom designed pbc... From the wall (with an 5v usb adapter plug and a micro-usb cable).
My question is:
I know I can solder a micro-usb socket, but I suposse that I should also put a level shifter of some sort to change the current to 3.3volts, right? If so, what do you recommend? Or what setup do you think will work best?
Thanks!
