Re: Powered ESP32 with 18650, LiPo, or button battery

Yes I understand, the output current 100 or 150mA is not enough and with the 4056, there is problably to much voltage

In your opinion, what's the best way for a portable powered solution, when we use WiFi with the ESP32 ?

Thanks.

For me after the micro USB input the card make a regulation voltage for reduce v...
