Questions
How big is the Ol75kb PCB?
It measures 325.8 × 105.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ol75kb use?
117 parts, built around the BAT54C. 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 Ol75kb KiCad files?
From the scottcjx/o60kb repository on GitHub, at the commit this page was made from: the board is hardware/keyboard-pcb/ol75kb/ol75kb.kicad_pcb and its schematic hardware/keyboard-pcb/ol60kb/key_matrix.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ol75kb design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
