Too hot to handle

Hi All,

I am starting with my first project with ESP8266. As soon as I connect chip to my laptop it is heating up a lot. In the first 2-3 tries, my laptop was throwing an error saying something like USB device needs more power and now it is not at all connecting to laptop. However, when I try to connect it again it is heating up a lot.

Can someone help/suggest what could be the issue and why this error has occurred?

Thanks in advance

Do not hijack. Thread split.

Always show us a good schematic of your proposed circuit.
Show us a good image of your ‘actual’ wiring.
Give links to components.

Wiring problem, possibly short-circuited connections, or even reversed polarity.

The ESP8266 is probably dead by now, and if you keep connecting it to the laptop, you might kill that too.

Not much to go on but.....

Assuming your ESP8266 has a USB input connector, and your connection is directly from your laptop, I would look at these:

  1. if anything else is connected to your board, disconnect it
  2. Inspect your board for bits of wire or some conductive material.

Do not reconnect your board to your laptop. 2 to 3 tries is enough to tell you; unless you find something definitely wrong reconnecting will only make things worse.
In general electronics don't heal once it bad it stays that way.

good indication that your ESP is looking in the direction of trash bin
