Questions
How big is the Lab5 project PCB?
It measures 120 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lab5 project use?
65 parts, built around the TCAN330D, AMS1117-3.3, CAT24C256LI and AOD4185. 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 Lab5 project KiCad files?
From the ttpy2845/KiCAD_Lab5 repository on GitHub, at the commit this page was made from: the board is Lab5_project.kicad_pcb and its schematic Lab5_project.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lab5 project design in my own project?
Its repository states no licence, so its author keeps all rights: ask ttpy2845 before reusing the design.
