Questions
How big is the New project adder PCB?
It measures 225.5 × 125.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the New project adder use?
87 parts. 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 New project adder KiCad files?
From the cieuoc/openelective-8bitadder repository on GitHub, at the commit this page was made from: the board is jesned/new project adder/new project adder.kicad_pcb and its schematic Ajith N/CIRCUIT/full adder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the New project adder design in my own project?
Its repository states no licence, so its author keeps all rights: ask cieuoc before reusing the design.
