Questions
How big is the KiCAD v4 PCB?
It measures 40.6 × 78.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the KiCAD v4 use?
48 parts, built around the NRF24L01P-R, DS3231MZ+, PCA9306D and BC847. 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 v4 KiCad files?
From the ARTS-Laboratory/SCUWLS repository on GitHub, at the commit this page was made from: the board is system_design/Georgetown/V0.2.0/EDA/main_board/KiCAD_v4/main_board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the KiCAD v4 design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
