Questions
How big is the AriCalculator RevC PCB?
It measures 76.2 × 147.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AriCalculator RevC use?
513 parts, built around the MC9S12G128, FT232RL, MCP1640-I/MC and MCP1643-I/MC. 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 AriCalculator RevC KiCad files?
From the hotwolf/AriCalculator repository on GitHub, at the commit this page was made from: the board is Hardware/RevC/PCB/KiCad/AriCalculator-RevC.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the AriCalculator RevC design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
