Questions
What parts does the Tatt use?
4 parts, built around the ATMEGA8-16AU and HV9930LG-G. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Tatt KiCad files?
From the d00p44/stuff repository on GitHub, at the commit this page was made from: the board is tatt/tatt.kicad_pcb and its schematic tatt/tatt.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tatt design in my own project?
Its repository states no licence, so its author keeps all rights: ask d00p44 before reusing the design.
