SmartPower2 burned

Post by yusion »

I received Smartpower2 today,and i use smartpower2 to monitor the energy consumption of xu4,it works. Everything as described in https://wiki.odroid.com/accessory/power ... martpower2
But a few hours later, when I re-measured, I found that after the power was plugged in, the smartpower2 started to smoke, the LCD no longer displayed, and the LED no longer flickered. Only the LED on the back of the LCD flashed red quickly.Image

How did you connect the XU4 board to the SmartPower2?
Did you buy the SmartPower2 from our web-store directly? or from a distributor?

i bought the Smartpower2 from your web-store directly.
The connection method is as follows, I did not connect HDMI to xu4. Only one mouse is connected to xu4.

The first few times can be measured normally, but when the measurement is continued in the afternoon, after plugging in the power, the board starts to smoke

Thank you for the picture and detail explanation. I couldn't find anything wrong.
We will help you soon.

BTW, is your XU4 still alive? Do you have a 5V/4A PSU to test the XU4 board?

yes,my xu4's still alive.
i have a 5V 4A PSU to test the XU4 board.
I have to send smartpower2 to Korea for warranty. Buying from Korea takes a long time to ship to my country. (12 days)
I'm not sure if the next smartpower2 will face this situation, so I only buy another smartpower2 as a spare.
Hope everything goes well, although it makes me sad.I eagerly hope to be able to measure power consumption

I unplugged the power cord on XU4 while XU4 was still running, and then unplugged the power cord on SmartPower2.
I don't know if this is the reason why smartpower2 burns up. (My English is not very good, I hope you can understand, thank you)

It should not make any hardware damage to the SmartPower2 nor the XU4.
But any sudden power disconnection could corrupt the file system in the SD card or eMMC.
Therefore, shut down the system with poweroff command gracefully and disconnect the power cables.
It will reduce the hardware damages too.

Anyway, we will ship a new SmartPower2 to you tomorrow and you receive it within few days probably.
Please ship the damaged one when you have time soon.

OMG,thanks you!!!
I will find time to send you the broken smartpower2, but it may be later. I have never sent anything to Korea.
I will contact my brother who is studying at Seoul National University as soon as possible and let him teach me how to send it to you.
Or I can send it to my brother first, and then let him send it to you. But it may take a long time.
I will write down my forum id in the package, and you will know that I delivered it when you see it

hi odroid,
I have sent the package via EMS. I hope it can be delivered to your company as soon as possible
But you know, due to the different export rules of each country, this package may fail to be sent to your company successfully ,and eventually EMS may return the package to me .
so If it comes true, can I keep the board ? :(
(I just prepare for the worst. Maybe the package can be delivered to your company successfully.) ;)

Don't worry.
Give me the EMS tracking number via PM(Private Message) and we will manage the customs clearance and taxes.

BTW, did you get a shipping notice from our sales team?
