How to program NodeMCU?

Question

Arduino

Good afternoon.
Please tell me what is the best way to program NodeMCU?
The fact is that the same script written in two languages ​​behaves differently.
That is, the pin for which the script is written in the Arduino IDE, with a logical unit, produces a stable 3.3V.
And in LUA - only 3V. And this is not enough to control the module. How can this be?

Answer 1

I strongly suspect that the cause must be sought in the compounds.
Or the lua script initializes much more peripherals, as a result, the power converter is not enough for everything.
