Questions
How big is the Shark1by3 PCB?
It measures 57.2 × 46 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Shark1by3 use?
30 parts, built around the ATMEGA32U4-AU and PRTR5V0U2X. 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 Shark1by3 KiCad files?
From the ar1a/shark1by3 repository on GitHub, at the commit this page was made from: the board is shark1by3.kicad_pcb and its schematic matrix.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Shark1by3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask ar1a before reusing the design.
