Questions
How big is the KiCad Schematic PCB?
It measures 54.9 × 54.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the KiCad Schematic use?
51 parts, built around the LM386 and MC7805BDTRKG. 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 Schematic KiCad files?
From the DDeGonge/TicTacToe-Bot repository on GitHub, at the commit this page was made from: the board is pcb_v1/KiCad Schematic.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the KiCad Schematic 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).
