Boards in 1 GitHub repository, designed in KiCad, that use the BC559B by Diotec Semiconductor (General-purpose PNP bipolar junction transistor in TO-92 package with 2.54mm pitch, manufactured by several semiconductor companies.). See how each wires it, with its parts, size, README and files; the BC559B’s symbol, footprint and pinout are on its own page.
