Questions
How big is the Pcb1.0 PCB?
It measures 121.9 × 43.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pcb1.0 use?
18 parts, built around the L293D. 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 Pcb1.0 KiCad files?
From the phorton1/Arduino-theClock repository on GitHub, at the commit this page was made from: the board is docs/kicad/pcb1.0/pcb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pcb1.0 design in my own project?
Its repository states no licence, so its author keeps all rights: ask phorton1 before reusing the design.
