Esp01 overheating

Deepti.
Deepti. 11 months ago

I am a college student and i just bought the esp01 module to get some hands-on experience and i tried to run a very basic code to just simply print a statement but it constantly shows avrdude errors and esp01 gets starts getting overheated as it gets power. Within 10 seconds it gets so hot that you can not touch it with bare hands. I dont initially i thought it must be some connection error or something but i rechecked it multiple times and i also tried using other esp and still the problem occured. 
can anyone please help fixing the avrdude error and overheating problem??

    Are you sure you're supplying the right voltage? ESP-01 modules are 3.3V and will definitely burn-up if subjected to 5V on a continuous basis. - Gough

    Are you sure that you power device correctly? This can happen if you swapt VCC and GND, for example.

    Post a photo of how you've connected your esp01 module as I too would've thought a shorted wire or reverse power connection.

    1. Change the board to generic esp8266 instead of Arduino UNO.

    2. If you are trying to program ESP with Arduino, make sure the power is provided on proper pins. Better option will be using a USB adapter as shown below with a press button attached to it.
