So I ordered more VL805 from #Aliexpress and those turned out to be exactly the same - fake chips that either do not work (do not get detected by Raspberry Pi 4B) or some of those were even shorted out of the box. Wow.

Also the marking on the fake ones gets washed away almost instantly with IPA.

I bought some 74LS Logic Chips from Ali Express. Guess what happened next?
