Hello community,

today I had a very strange phenomenon. The board is supplied via 24V and so far everything ran without errors. now I wanted to connect the USB cable to the computer to change something in the config. Suddenly there was a bit of a sticky smell and I pulled the USB plug out. The plug that was in the PC and the whole cable were very hot. Short circuit? Only the VBB LED lights up on the board. All other LEDs remain dark and the board does not start up.
