I bought arduino nano v3(mega 328, CH340G) from China. And the same evening wanted to test it.
Started to seek for mini-b usb. And was happy, when except cabel i found the charger else(attachment below).
Then i uploaded blink example. And it worked brilliantly.
Next i dicided to use charger. I was thinking , that it gives direct 5v.
And without any testing justs plugged it into arduino. And it was still working fine.
But now when i connect nano to pc, pc doesn’t recognise it at all. No reaction.
When connect charger nano doesn’t work too, even little lamp doesn’t light.
What could it be? Can i repair it?
