This sadly never worked, and it also pulled a LOT of current (>2A), so I've abandoned it. D

Questions
How big is the 16x16display PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 16x16display use?
41 parts, built around the 74HC138, 7130LA55PDGI and 86093967113745ELF. 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 16x16display KiCad files?
From the TechPaula/DCJ11Hack- repository on GitHub, at the commit this page was made from: the board is Display 16x16/16x16display.kicad_pcb and its schematic CPU Board/InvLED.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 16x16display design in my own project?
Its repository states no licence, so its author keeps all rights: ask TechPaula before reusing the design.
