Re: part number of U7 in PICKIT 4
You're right. One time I blew up Mikroprog programmer because of ground isolation failure. All components were ok except one with a damn QFN package! but I got it working. After that, it was easy to repair that.
I ordered one, but I will try to repair it to see what can get damaged.
One more question, How did you manage to find the part from its marks? I know there are some search engines online, I tried them; useless!
