Questions
How big is the Chessboard pcb PCB?
It measures 247.5 × 71 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Chessboard pcb use?
29 parts, built around the CD74HC4067M, A4988 and IRLZ34N. 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 Chessboard pcb KiCad files?
From the EmilAAS/BlitzMate repository on GitHub, at the commit this page was made from: the board is chessboard_pcb/chessboard_pcb.kicad_pcb and its schematic chessboard_pcb/chessboard_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Chessboard pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask EmilAAS before reusing the design.
