Questions
How big is the Controller from scratch PCB?
It measures 89.5 × 88.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Controller from scratch use?
44 parts, built around the ESP32-C3-WROOM-02-H4. 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 Controller from scratch KiCad files?
From the plastuchino/hack-controller repository on GitHub, at the commit this page was made from: the board is controller_from_scratch.kicad_pcb and its schematic controller_from_scratch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Controller from scratch design in my own project?
Its repository states no licence, so its author keeps all rights: ask plastuchino before reusing the design.
