Questions
How big is the Arduino Uno SMD PCB?
It measures 68.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Arduino Uno SMD use?
52 parts, built around the ATMEGA16U2-MU, PY32F030K28U6TR, LMV358IDGKR 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 SMD KiCad files?
From the kaustubh850/ARMduino-UNO-PY32 repository on GitHub, at the commit this page was made from: the board is PY32F030/KiCAD Project Files/Arduino Uno SMD.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Arduino Uno SMD design in my own project?
Its repository states no licence, so its author keeps all rights: ask kaustubh850 before reusing the design.
