How to connect 12v battery with Nano esp 32? when I connect direct battery connect with nano esp 32 it is getting heat..
You connected battery to VIN and GND ?
yes..as per datasheet vin range is 6v to 21v.
Yes.
Do you have something wired to other pins?
What else do you have connected?
no.. I was used 3s 3500Mah li-ion battery,breadboard,and jumperwire... when i connected 12v and gnd on nano esp 32 vin and gnd pin it was getting heat.. after that I was used 9V/1.5A power adapter it will also heat and after that port connection was not showed on arduino ide.
Something wrong with the breadboard? You know how to use them? Bad soldering on pin headers?
How hot is it getting?
Too hot to touch?
no I also changed that breadboard and use new one same problem happpened
Bad soldering on pin headers?
yes too hot after touch
Well it should not get that hot. I suspect you somehow damaged your nanoesp32
Does it work with just the USB connected?
no, I received microcontroller with pin header
previously it was ok work on usb but when I connected with battery it was getting heat and damage
Not sure what you did wrong but if it no longer works on USB it seems it is damaged.
so how to connect battery with nano esp 32 with new one
In theory you connected it correctly. In practice something went wrong.
Are you sure it's genuine nano esp32? Not just some esp32??
Is it an official Arduino Nano ESP32 or a clone?
I purchased this Microcontroller from Robu.in. and how to check is it clone or original product?
If it was this one, then it is apparently an official Arduino
