Questions
How big is the ACE keyboard PCB?
It measures 320 × 108 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ACE keyboard use?
64 parts, built around the 74LS245SC and KP8. 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 ACE keyboard KiCad files?
From the andriodious/Jupiter_Ace_External_Keyboard_PCB repository on GitHub, at the commit this page was made from: the board is Ace_External_Keyboard/ACE-keyboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ACE keyboard design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
