don't worry it works because of voltage regulator 1117c that can take maximum input up to 15v. But for safety you should use less than 10v with good quality power supply.
What happened to your NodeMCU I am getting the fatal error like A fatal error occurred: Could not connect to an Espressif device on any of the 1 available serial ports
Yes bro it is a fully fake video node mcu needs 3.3v constant supply to run you can give it 5v through its usb it has has built in step down voltage regulator so it will run perfectly

@@WOW_EDITING you mean, we can power it with 3.3-9 v from its Vin therminal even the all sources said that the powering range for Vin is between 7v-12v??
Always use a motor diver. Don't attempt to run the motor directly from the microcontroller.even the motor voltage and microcontroller voltage are same.

Useful tip. thanks for sharing.
my 3 nodemcu just destroyed after giving 12v

Exactly the same thing

Bro, Can i use logic level shifter along with esp32 module to detect high frequency square wave having amplitude 5v?And will it affect accuracy?
DON'T TRY THIS MY ESP32 GOT DESTROYED!!

This is what happens when you don’t have any knowledge of electricity, you burn your electronics!
Thank you
to which pin should i connect the 12 volt??
Vin
@@thesrijan49 very thanks
Can I use normal mobile charger with 5v and 2A, through the usb port?
yes, you can
DON'T DO THIS! IT WILL FRY YOUR BOARD OR EVEN CAUSE A FIRE
My esp32 board shorted when goving12v
My node mcu destroyed
Ofc it did, the power input is 3v-3.6v and the current is 80mA, am i right guys ?
@@alexandrusandu1249 You can power it with 3.3-9 v no issues ...dont go for 12

Hey my NodeMCU is getting an error like
A fatal error occurred: Could not connect to an Espressif device on any of the 1 available serial ports
you are providing 12v AND HOW much current ?
The resistance between Vin and G is 25Mohm, so the current is 480nA
my esp32 burnt after put 12v
mine hibiscus also terkorban after putting 12v
is it okay if i power nodemcu and 5v stepper motor from 9v battery ? (Stepper's max input voltage is 12V)
Yes possible
@@thinkar4873 thanks, will try that

Don't attempt to run the motor directly from the microcontroller.even the motor voltage and microcontroller voltage are same.
do not do this,mine destroyed after giving it less than 9 volts through the VIN.
same
How u know it's destroyed
you can't do that for a long time.
Nice try bro👍
Now unplug it and plug it back in bet you’ll get smoke did this by mistake last night 😅 killed 5 mcu in one night
