Questions
How big is the Arduino uno board PCB?
It measures 68.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Arduino uno board use?
65 parts, built around the ATMEGA16U2-MU, ATMEGA328P-PU, LMV358 and LP2985-33DBV. 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 Arduino uno board KiCad files?
From the goodboy-kwame/Arduino-Uno repository on GitHub, at the commit this page was made from: the board is Ebenezer Banafo-01230492B/arduino uno board.kicad_pcb and its schematic Ebenezer Banafo-01230492B/assignment (2).kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Arduino uno board design in my own project?
Its repository states no licence, so its author keeps all rights: ask goodboy-kwame before reusing the design.
