Questions
How big is the TruthTable PCB?
It measures 20 × 110 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TruthTable use?
26 parts, built around the 74HC14, 74LS153DC and L7805. 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 TruthTable KiCad files?
From the attoparsec/TruthTable repository on GitHub, at the commit this page was made from: the board is TruthTable.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the TruthTable design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
