Questions
How big is the Assets PCB?
It measures 76.2 × 29.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Assets use?
16 parts. 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 Assets KiCad files?
From the pvginkel/Intercom repository on GitHub, at the commit this page was made from: the board is assets/Boards/Main/Main.kicad_pcb and its schematic assets/Boards/Control/Control.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Assets design in my own project?
Its repository states no licence, so its author keeps all rights: ask pvginkel before reusing the design.
