SMD marking codes database
This site:
https://smd.yooneed.one/
was mentioned on the Piclist email list. I tried it with a couple of parts on the SMT Grandson of Zerobeat kit:

The voltage regulator is marked F5 8B although it is hard to see, the series protection diode is marked: M7
I *sorta* found them in the database but you kinda have to know the package type and the part type to pick from all the choices.
Still it might be handy when looking at a commercial board that needs fixing.
