Hi, I ordered a mini USB breakout board and carefully (I thought) soldered a 5 pin header to the board (VCC, D-, D+, ID, GND).
To test it I hooked it to a PC USB port with a USB to mini USB cable and checked it with a scope (probe to VCC and probe ground to GND). My scope showed 5 volts as expected but within a minute or so I smelled something burning and saw a bit of smoke coming from the board. I can see that the board trace from the USB connector to the VCC pin is burned.
I'm presuming that simply probing the board shouldn't cause it to heat up and burn, right? So maybe I damaged the board when soldering the header, or maybe the board was defective? What do you think?
Thanks, EF
