Questions
How big is the TP AVR PCB?
It measures 42.4 × 60.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TP AVR use?
32 parts, built around the 74HC238D. 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 TP AVR KiCad files?
From the Michael-Lloyd/NotTP_AVR repository on GitHub, at the commit this page was made from: the board is TP_AVR/TP_AVR.kicad_pcb and its schematic TP_AVR/TP_AVR.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TP AVR design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
