Questions
How big is the Wederian PCB?
It measures 56 × 46 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wederian use?
31 parts, built around the ATMEGA16U4-AU, SHT31-DIS-F and CG0603MLC-05E. 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 Wederian KiCad files?
From the io7m/wederian repository on GitHub, at the commit this page was made from: the board is wederian.kicad_pcb and its schematic icsp.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wederian design in my own project?
Its repository states no licence, so its author keeps all rights: ask io7m before reusing the design.
