Questions
How big is the RPN Scientific Calculator PCB?
It measures 62.2 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RPN Scientific Calculator use?
86 parts, built around the 2N7002H and AO3415A. 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 RPN Scientific Calculator KiCad files?
From the ice458/RPN_Scientific_Calc repository on GitHub, at the commit this page was made from: the board is hardware/RPN_Scientific_Calculator.kicad_pcb and its schematic hardware/RPN_Scientific_Calculator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RPN Scientific Calculator 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).
