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?
69 parts, built around the ATMEGA16U2-MU, ATMEGA328P-MU, BMP280 and LMV358IDGKR. 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/ArduinoEquipped repository on GitHub, at the commit this page was made from: the board is Arduino Uno IMU+BMP280/kaustubh850 ArduinoEquipped main Arduino Uno IMU+BMP280/Arduino Uno SMD.kicad_pcb and its schematic Arduino Uno IMU + BMP280 + 3.3V I2C/ATMEGA328P-MU.kicad_sch. 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.
