Questions
How big is the Tutorialextra PCB?
It measures 75 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tutorialextra use?
57 parts, built around the STM32F103C8T6, AMS1117-3.3 and MCP2542FD. 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 Tutorialextra KiCad files?
From the Zader8/PCB-Tutorial repository on GitHub, at the commit this page was made from: the board is tutorial-backups/tutorialextra.kicad_pcb and its schematic tutorial.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tutorialextra design in my own project?
Its repository states no licence, so its author keeps all rights: ask Zader8 before reusing the design.
