- Sun Apr 26, 2020 5:24 pm #86774 I have a NodeMCU and I need power it with 5V without use USB, only by PIN.
Is it possible?
My NodeMCU have a Vin and a VV pin.
Can you explane me the different between Vin and VV pin? Can I use one of these to power NodeMCU with 5V?

The VV pin is not standard and I guess it is related to the ADC, you would have to trace it on your module or find a schematic for it.
