After a normal USB plug-in and unplugging, my UNO Q development board broke. The power indicator light is not on, and it displays that the USB output current exceeds the limit, making it unusable. It seems that the quality of the UNO Q is not as good as other models.

I also burned mine, but that was totally my fault - I put 19V to system 5V pin and after some smoking it was obviously dead. But before it was quite stable. Looking forward to 4Gb model, when can I order it please?

I popped one as well. As with extender777 I blame myself. I plugged in to a high power USB-C dock on the computer connection. I'm not sure that the Uno Q is more fragile than other Uno, as I've popped quite a few different ones in my time.

I was using it normally, and then it broke.

Just plug in the USB and run the program, it works. Unplug the USB, plug it in again, and then it broke.
