How big is the Master system controller PCB?
It measures 112.4 × 59.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Master system controller use?
16 parts. 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 Master system controller KiCad files?
From the sparkletron/master_system_controller repository on GitHub, at the commit this page was made from: the board is schematic/master_system_controller.kicad_pcb and its schematic schematic/master_system_controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Master system controller 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).
