Questions
How big is the PCB course PCB?
It measures 80.5 × 62 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PCB course use?
73 parts, built around the AD8039ARZ, LM7805MPX, NE555D and DMN10H700S-7. 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 PCB course KiCad files?
From the seankyer/QuickSig repository on GitHub, at the commit this page was made from: the board is PCB_course.kicad_pcb and its schematic PCB_course.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCB course design in my own project?
Its repository states no licence, so its author keeps all rights: ask seankyer before reusing the design.
