Questions
How big is the PCB Keys PCB?
It measures 310 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PCB Keys use?
135 parts, built around the MMA8452QT. 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 PCB Keys KiCad files?
From the g200kg/multiribbon repository on GitHub, at the commit this page was made from: the board is PCB/PCB_Keys/PCB_Keys.kicad_pcb and its schematic PCB/PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCB Keys 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).
