Connecting ESP32 to an external power source

Yes, until the battery is dead.

Thank.
Please can you tutor me on somethings? If you don't mind.

That depends on what you need to know

How can I contact you please?

Right here.
I'm on the forum almost every day at least for a few hours.

If you need help with code, someone else would be a better choice.

Not much of coding, but electronics

So what are your questions?

Can it be private please ? Like through email

Sorry no.

See Post #3 and have it moved to paid/jobs which are as private as you want. @zwieblum

Interesting story line... first "new" then "final year" then "don't know how" then design a standalone mcu, then "private" work, but not bitcoin... got it.
