ESP 12f needs 5v not 3.3 (In my case)

By Joe Job
- Sat Dec 10, 2016 5:21 pm #59334 So I have had many issues with the 12f since trying to convert my 01 devices to 12f. The main were:

OTA updates would work on the 01 and not on the 12f with the same code.
Constant crashing on the 12f.
12f could not be powered by anything lower than a 12v running through a 3.3v reg, 5v volt running through a 3.3 reg would not work.

I have since switched my programmer to 5v and not 3.3v.

Result:

OTA now works.
No crashing.
Can run the device from a 5v input without a 3.3 reg.

The answer was simple, after all the loops I was told to jump through, the simple answer was change the voltage to 5v, now I can continue :D
