Questions
How big is the Screwduino PCB?
It measures 99 × 49 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Screwduino use?
31 parts, built around the ATMEGA328-PU and AP1117DG. 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 Screwduino KiCad files?
From the land-boards/lb-boards repository on GitHub, at the commit this page was made from: the board is Arduino Cards/Screwduino/Screwduino X5/screwduino.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Screwduino design in my own project?
Its repository states no licence, so its author keeps all rights: ask land-boards before reusing the design.
