Connected Yarns wrong -> fried?

now i have done it the first time, connected a module wrongly in a hurry …Yarns now doesn’t do anything, is there something to save in that case or is it a candidate for the bin ?

Never bin anything like that. I would expect it is protected against reverse voltage, but still possible to do damage.

I would expect that a protection diode and/or voltage regulator will be damaged.

thanks, had a closer look and D1 (diode) was the culprit. quite relieved (-;
