Questions
How big is the Atmega328p PCB?
It measures 79 × 52 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Atmega328p use?
18 parts, built around the ATMEGA328P-PU and L7805. 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 Atmega328p KiCad files?
From the Vtechcode/ATMEGA328P_custom_pcb repository on GitHub, at the commit this page was made from: the board is atmega328p.kicad_pcb and its schematic atmega328p.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Atmega328p design in my own project?
Its repository states no licence, so its author keeps all rights: ask Vtechcode before reusing the design.
