Questions

How big is the FolderStructure PCB?

It measures 79.4 × 40.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the FolderStructure use?

22 parts, built around the ATTINY1626-XF, BC807 and MMBT2222A. 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 FolderStructure KiCad files?

From the grodnay-riil/EasyEDA_Lib repository on GitHub, at the commit this page was made from: the board is plugins/com_github_gauravmm_hierarchicalpcb/examples/TripleRecursion/FolderStructure.kicad_pcb and its schematic plugins/com_github_gauravmm_hierarchicalpcb/examples/FlatStructure/FlatStructure.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the FolderStructure design in my own project?

Its repository states no licence, so its author keeps all rights: ask grodnay-riil before reusing the design.
