Questions
How big is the Final project PCB?
It measures 77.9 × 21.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Final project use?
56 parts, built around the ATMEGA328P-AU, CH340E, FM1208S 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 Final project KiCad files?
From the Andy-Cheng1017/BlanceCarProject repository on GitHub, at the commit this page was made from: the board is Circuit V1/final project/final project.kicad_pcb and its schematic Circuit V2/final project/final project.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Final project design in my own project?
Its repository states no licence, so its author keeps all rights: ask Andy-Cheng1017 before reusing the design.
