ESP8266 Community Forum

- Thu Sep 24, 2015 8:29 am #29775 Bonjour ,

i have read in this forum that it's possible to powered ESP8266 with 5v battery ( USB Charger) and tree diodes (LED ?).

5v - 3* 0.6 = 3,2V.

How to do that ?

Thanks for help , link or other info.

Please use a proper voltage regulator.

A buck converter is even better.

No rectifyer diodes black 1N4001 diodes connected in series.
Not the recommended method.
