Questions
How big is the Schrackduino UNO PCB?
It measures 68.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Schrackduino UNO use?
58 parts, built around the ATMEGA16U2-MU, ATMEGA328P-PU, 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 Schrackduino UNO KiCad files?
From the ckfnr/Schrackduino repository on GitHub, at the commit this page was made from: the board is Schrackduino UNO.kicad_pcb and its schematic ATMEGA328P-PU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Schrackduino UNO design in my own project?
Its repository states no licence, so its author keeps all rights: ask ckfnr before reusing the design.
