Questions
How big is the Repl board PCB?
It measures 55.5 × 32.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Repl board use?
25 parts, built around the ATMEGA32U2-AU, SN74HC42D and CG0603MLC-05E. 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 Repl board KiCad files?
From the TweetyDaBird/Filco-TKL-Controller repository on GitHub, at the commit this page was made from: the board is PCB/repl board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Repl board design in my own project?
Its repository states no licence, so its author keeps all rights: ask TweetyDaBird before reusing the design.
