Questions
How big is the MXKeyboard PCB?
It measures 433.1 × 135.9 mm and has 6 copper layers, 1.6 mm thick.
What parts does the MXKeyboard use?
401 parts, built around the ATXMEGA256A3U-MH, TLC5947RHBT, 74HC238BQ and TJ-S1615SW6TGLCCYRGB-A5. 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 MXKeyboard KiCad files?
From the bad-alloc-heavy-industries/MXKeyboard repository on GitHub, at the commit this page was made from: the board is hardware/MXKeyboard.kicad_pcb and its schematic hardware/Column_decode.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MXKeyboard design in my own project?
Its repository publishes it under the BSD-3-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
