Questions
How big is the Accelerator PCB?
It measures 221.5 × 172.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Accelerator use?
279 parts, built around the ATMEGA32U4-MU, SK6812MINI-E, ESD5Z5V0 and SMD0805-050-16V. 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 Accelerator KiCad files?
From the bbrfkr/accelerator-keyboard repository on GitHub, at the commit this page was made from: the board is accelerator.kicad_pcb and its schematic accelerator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Accelerator design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
