[Solved!] Smoke from mkr1000

I made a thing with arduino mkr1000, and I plug it in and it lets out some smoke, so I quickly unplug it. The arduino is really hot. What do I do?

Edit: For anyone else with the same problem, I fixed it by just waiting it out. Make sure to unplug ground to stop the circuit from running completely, because the first priority is probably getting the arduino working. Good luck!

Hi,
Welcome to the forum.

Where did the smoke come out from?
What were you making?
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
Can you post a picture of the controller where you think it got hot?

Can you program the controller on its own after the smoke came out?

Can you tell us your electronics, programming, arduino, hardware experience?

Thanks.. Tom... :slight_smile:

Leave it uplugged.

Check your circuit.

Its very difficult to get the smoke back in.

What were you making?

A simple game with an lcd screen and a button

Can you post a picture of the controller where you think it got hot?

Where the smoke came from

No. Plugging it in (after it had cooled down) just puts a notification on my mac saying it had "disabled usb devices because it was using too much power"

Can you tell us your electronics, programming, arduino, hardware experience?

Not much

The part that blistered is a dual P-channel FET and forms part of the power input front end; it's used as part of the circuit that selects between USB power or VIN.

All of the current for the MKR1000 and anything you're powering from it will go through one of those two devices. I suspect you've got an error in your wiring (have a short somewhere) or are trying to power something that draws much more current than the power circuit of the MKR is designed for.

Can you show a drawing of your circuit? What is connected to what? Specifically, what is connected to pin 14 (+5V)?

It will tell you how to post pictures into your posts, so everyone can see.

Yes, this is power switch USB/VIN. In any case, the smoke is not good sign. I'm recommending to use external power source first, for any further testing.

Thank you all for your assistance!

First off, I found that, yes, I had a short.

Second, after leaving it to cool for awhile, she's alive again!

What I have gotten out of this:

  • A mild finger burn
  • That I should check for shorts before supplying power
    Once again, thank you all, and have a good day! :grin:

Hi,
Good to hear.
I've given you a Karma for putting SOLVED in your subject and letting us know the result and carnage the problem caused.
