Questions
How big is the AnalogComputer PCB?
It measures 120.7 × 80 mm and has 4 copper layers, 1.6 mm thick.
What parts does the AnalogComputer use?
113 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 AnalogComputer KiCad files?
From the mwwhited/EmbeddedBakery repository on GitHub, at the commit this page was made from: the board is circuits/AnalogCalculator/AnalogComputer/AnalogComputer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the AnalogComputer design in my own project?
Its repository states no licence, so its author keeps all rights: ask mwwhited before reusing the design.
