Questions
How big is the Calculator PCB?
It measures 69.9 × 35.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Calculator use?
11 parts, built around the MAX7219M. 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 Calculator KiCad files?
From the boombuler/progcalculator repository on GitHub, at the commit this page was made from: the board is hardware/calculator/calculator.kicad_pcb and its schematic hardware/calculator/calculator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Calculator design in my own project?
Its repository states no licence, so its author keeps all rights: ask boombuler before reusing the design.
