Questions
How big is the Wingnote PCB?
It measures 162.3 × 64.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wingnote use?
82 parts, built around the DS28E17Q+T, MAX7325AEG+, ST25R3918-AQWT and BQ25173DSG. 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 Wingnote KiCad files?
From the TinyTinfoil/wingnote-pcb repository on GitHub, at the commit this page was made from: the board is wingnote.kicad_pcb and its schematic b.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wingnote design in my own project?
Its repository states no licence, so its author keeps all rights: ask TinyTinfoil before reusing the design.
