Questions
How big is the Chess board PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Chess board use?
102 parts, built around the MFRC52202HN1,151 and SN74HC595N. 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 Chess board KiCad files?
From the EmilEmilchen/chess-board repository on GitHub, at the commit this page was made from: the board is board.kicad_pcb and its schematic Reference/Sample Project KiCad/AeonLabs-PCB-Shields-RFID-NFC-RC522-main/MFRC522 RFID NFC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Chess board design in my own project?
Its repository states no licence, so its author keeps all rights: ask EmilEmilchen before reusing the design.
