Questions

How big is the Inc dec PCB?

It measures 99 × 58 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Inc dec use?

72 parts, built around the LM324. 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 Inc dec KiCad files?

From the ssloy/ternary repository on GitHub, at the commit this page was made from: the board is ALU/RR/inc-dec/inc-dec.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Inc dec design in my own project?

Its repository states no licence, so its author keeps all rights: ask ssloy before reusing the design.
