Questions
How big is the TD4 PCB?
It measures 137.2 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TD4 use?
55 parts, built around the 74LS161DC, 74HC153D, 74HC14 and 74HC283P-E. 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 TD4 KiCad files?
From the s5suzuki/TD4 repository on GitHub, at the commit this page was made from: the board is td4/td4.kicad_pcb and its schematic td4/clock_reset.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TD4 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
