Questions
What parts does the Notahawk use?
50 parts, built around the ESP32-C3, TSR 1-2433SM, BMP581 and W25Q128JVSIQ. 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 Notahawk KiCad files?
From the bimmui/notahawk repository on GitHub, at the commit this page was made from: the board is notahawk-pcb/notahawk/notahawk.kicad_pcb and its schematic notahawk-pcb/notahawk/notahawk.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Notahawk design in my own project?
Its repository states no licence, so its author keeps all rights: ask bimmui before reusing the design.
