Questions
How big is the KiCad Final PCB?
It measures 93 × 74 mm and has 2 copper layers, 1.6 mm thick.
What parts does the KiCad Final use?
21 parts, built around the ATMEGA328PB-AU, ROB-14450, 74HC595D,118 and BMI160. 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 KiCad Final KiCad files?
From the NarekKalikian/Microcontroller-Projects repository on GitHub, at the commit this page was made from: the board is FinalProject/KiCad Project Files/KiCad_Final.kicad_pcb and its schematic FinalProject/KiCad Project Files/KiCad_Final.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the KiCad Final 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).
