Questions
How big is the Dendy PCB?
It measures 91 × 186.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dendy use?
141 parts, built around the 74HC368D, 74LS373SC, 4558D and LM2596T-ADJ. 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 Dendy KiCad files?
From the UzixLS/dendy repository on GitHub, at the commit this page was made from: the board is pcb/rev.A/dendy.kicad_pcb and its schematic pcb/rev.A/dendy.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dendy design in my own project?
Its repository states no licence, so its author keeps all rights: ask UzixLS before reusing the design.
