Questions
How big is the Lab2 project PCB?
It measures 80 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lab2 project use?
45 parts, built around the 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 Lab2 project KiCad files?
From the ttpy2845/KiCAD_Lab2 repository on GitHub, at the commit this page was made from: the board is Lab2_project.kicad_pcb and its schematic Lab2_project.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lab2 project design in my own project?
Its repository states no licence, so its author keeps all rights: ask ttpy2845 before reusing the design.
