Questions
How big is the DangerDoughnut PCB?
It measures 50 × 37 mm and has 4 copper layers, 1.61 mm thick.
What parts does the DangerDoughnut use?
281 parts, built around the ESP32-S3, ESP8285H16, 2450FM07D0034T and L5973D. 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 DangerDoughnut KiCad files?
From the gavin4d/dangerDoughnut repository on GitHub, at the commit this page was made from: the board is PCB/DangerDoughnut/DangerDoughnut.kicad_pcb and its schematic PCB/DangerDoughnut/DangerDoughnut.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DangerDoughnut design in my own project?
Its repository states no licence, so its author keeps all rights: ask gavin4d before reusing the design.
