Questions
How big is the Skateboard PCB?
It measures 83.6 × 84.8 mm and has 4 copper layers, 1.67 mm thick.
What parts does the Skateboard use?
186 parts, built around the ESP32-S3-WROOM-1-N8, SIT1042AQT/3, INA240A2PW and LMR16030SDDAR. 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 Skateboard KiCad files?
From the 86kkd/millionBoard repository on GitHub, at the commit this page was made from: the board is pcb/skateboard.kicad_pcb and its schematic pcb/GPS_Audio.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Skateboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask 86kkd before reusing the design.
