Questions
How big is the Hirerchy test PCB?
It measures 55.9 × 25.4 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Hirerchy test use?
24 parts, built around the NE555D. 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 Hirerchy test KiCad files?
From the Arvind595/KiCAD-Drafts repository on GitHub, at the commit this page was made from: the board is test_Jig/hirerchy_test/hirerchy_test.kicad_pcb and its schematic RCU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hirerchy test 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).
