smoke coming out of my beagleboard

Hi,

I plug a 9V power into the beagleboard and I see smoke coming out. Does it mean my beagleboard is broken?

I also am not able to connect to it using minicom anymore.

Could someone please tell me how I can check if my beagleboard is still funcitoning?

If it is for some reasons, broken, could someone please tell me if there is anyway I can repair it?

Please help me.

Thanks and Regards,

Yes. BeagleBoard will be destroyed by > 5V. From system reference manual:

WARNING: DO NOT PLUG IN ANYTHING BUT 5V TO THE DC
CONNECTOR OR THE BOARD WILL BE DAMAGED!

-> Repair -> RMA request

Dirk

most probably the demaged part is TPS2141 you can replace that and U2
3.3V regulator . you need to replace that

Hi
Is there anywhere that I can buy that TPS2141 part and the U2 3.3 V regulator?

How can I know which part is which?

Any help will be appreicated.

thanks,

My suggestion is that you do an RMA. If you want to try, you can buy the parts from DigiKey. The BOM is availble for download. If replacing the parts does not work or there is other damage on the board, it will not be repaird by Beagleboard.org as you will have violated the warranty. Even though that is what you have already done by not reading the manual and plugging in a 9V supply, we try to repair the board if possible. Sometimes it is beyond repair depending on how long people watch as the smoke rises from the board.

Hello,

I've just made the same mistake even though I had seen the
warnings in the manual and the big sticker on the connector,
so there's really no excuse. I realized what I was doing right
after I inserted the plug but it was too late. I didn't actually
see the smoke but sensed the smell and the TPS65950 was
very hot.

I wonder if I can still do an RMA since as you state above
I have violated the warranty by plugging in a 9V supply. I
would really appreciate it if I could.

If it isn't possible I'd like to know if there is any way to
diagnose the ICs to figure out what has been burnt.

Thanks in advance

You may be able to diagnose the blown up parts, but you most likely will not be able to repair a .4mm pitch BGA yourself. I would go ahead and request an RMA, take the abuse, and see if they are willing to fix it.

Hello Gerald,

Do you by any chance know how the billing part works?
Because I'm in Argentina and I think the costs for "sending
the board" + "return shipment" + "customs fees" may be
near half the cost of buying a new one.
Also, the people at the Company I work for (as an intern)
say they will be able to replace the TPS2141 or even the
TPS65950 but they'll do it only IF I'm sure of what went
wrong.
I've been trying to do some measures with a regulable
current limit power source (at 5V) and there's definitely
a short circuit (voltage drops to 3.2V@800mA limit).

Thank you

Typically there are no duties on the board when sent in for repair and returned. Only the initial shipping charges to the repair site.

Most likely the issue is U1 and maybe U2. Depending on how long you watched the board burn, it could also affect the OMAP3530, which of course will take the memory with it. If you want to try and repair it, give it a shot.

Gerald

I've just sent the RMA. Let's see what happens.

Thanks for your support and fast response!

Martin

So, how was the RMA response!

Gerald

issue=First time connected to 9V for 5 seconds.
I have posted a message to google group, they
advised me to request RMA.

Response:

"I see. We will see if we can fix it if you promise
not to do it again. "

And I will definitely not do it again! (I hope) :slight_smile:

Thank you very much!

Martin

I already knew the response. In fact, I knew it before you did!

Gerald

I was beginning to suspect that! Now I feel
like such a child!!

Martin

No need to. In fact, just the opposite. You would be surprised how many people blow up these boards and them make excuses, like “It came this way” or “They sent the wrong supply”, or “I didn’t see the label”. It is VERY refreshing to have someone like you thta tells the truth! We will take care of you!

But don't start a "who can apply the highest voltage and get away with it"
contest this way:-)
