Esp32 cam overheating

Postby Daveyman123 » Sun Jun 16, 2019 5:42 pm

My esp32 cam gets too hot to touch. I am not sure which part gets hot right now. I don't think there are any solder bridges. If I plug in a programmer board it gets too hot to touch instead. If I plug in 5v from a battery the esp32 cam gets too hot to touch. Nothing is plugged in to any pins. How do I troubleshoot further?


Thanks,
David

Which part specifically gets too hot? What's the code you're running on it? Does the board otherwise still function? What is the power draw of the board?

I am not sure which part overheated. I was EXTREMELY hot though. and I ended up purchasing some more of the esp32 cam boards on amazon.

please help!

I figured out that it is likely the sketch that is causing the issue. I have two devices now overheating. However, I am not sure how to upload a new sketch as the board is no longer recognized.

You should be able to override that by using a jumper wire to connect GPIO0 to ground, holding the reset button, and then plugging the module in. Wait a second, release the reset button and you should be able to reflash the board. I'm curious to what the sketch does; apart from e.g. using an I/O as an output while the external hardware also sets a level on it, I haven't seen an ESP32 act in such a fashion before.

Here is the sketch I used. I uploaded it using the dev module board setting as well as with 80mhz and 112500 speed. I uploaded with 3v and then provided 5v to the board to run the sketch. The sketch runs but prints out gibberish.

Here is a schematic of the board
