Questions
How big is the Intro to PCB PCB?
It measures 79 × 50.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Intro to PCB use?
45 parts, built around the ATMEGA328P-AU, FT232RL, LM1117T-ADJ and ESD9B5.0ST5G. 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 Intro to PCB KiCad files?
From the Rubeez1/Intro_PCB repository on GitHub, at the commit this page was made from: the board is intro_to_PCB.kicad_pcb and its schematic intro_to_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Intro to PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask Rubeez1 before reusing the design.
