The chip on my Up Squared V2 burnt out, but I don't know which chip it is.

• I'm sorry, I put it in the wrong category. Actually, what I have is an Up Squared V2.

I have an Up Squared V2 that I use as an ROV controller. It was running really well until today when I unplugged the 12V power cable, as recommended. When I reconnected the power cable, the IC chip burnt out. I don't know what the IC is or what caused it. I have attached a picture below.

Hi Sir,

For repaired motherboards, we have repair pipes.
The way is as follows

Thank you for your reply, Wilbert! I will start the return process soon.

However, I would like to confirm what caused the IC chip to burn. We have tested the power supply and found that it is working properly, so do you think there could be any other reason for this?

Additionally, could you explain a bit about what the IC chip does or its purpose?

I really want to prevent this problem from happening again in the future.

Hi Sir,

This IC is a Power IC that provides 5V for some parts.
Where this 5V power is useful:
SATA Power, CN3 5V Power, CN17 5V Power, 5V HDMI Power.
It has been confirmed that this is the first time that this IC has burned out since mass production. Since the occurrence rate is so low, it is temporarily impossible to deduce which IO caused it.

Best Regards,
Wilbert Lee.

Hi Wilbert,

That information is really useful. I connected some of device into the board. I will considering what can cause this problem from your information. Thanks Wilbert!

First, inspect the board for any visible signs of damage or burning around the chips. This could include discoloration, melting, or charring. If you find any evidence of damage, it's likely that the chip in that area is the one that burned out.

If there are no visible signs of damage, you can try using a multimeter to test the continuity of each chip on the board.
