Questions
How big is the Finalproj PCB?
It measures 82.2 × 87.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Finalproj use?
43 parts, built around the STM32F103C8T6 and AMS1117-3.3. 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 Finalproj KiCad files?
From the rileycyeoman/buttonPress repository on GitHub, at the commit this page was made from: the board is finalproj.kicad_pcb and its schematic BotPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Finalproj design in my own project?
Its repository states no licence, so its author keeps all rights: ask rileycyeoman before reusing the design.
