Questions
How big is the Ornithopter KiCad PCB?
It measures 63.5 × 60.4 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Ornithopter KiCad use?
56 parts, built around the ESP32-S3-WROOM-1-N8, SN74LV1T34DBV, INA240A1PW and DRV8320RSRHAR. 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 Ornithopter KiCad KiCad files?
From the ChrisLeoLeo/FOC-controller repository on GitHub, at the commit this page was made from: the board is Ornithopter KiCad - 4 Layer - Better Routing - Opamp V1/Ornithopter KiCad.kicad_pcb and its schematic Ornithopter KiCad - 4 Layer - Better Routing - Opamp V1/Ornithopter KiCad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ornithopter KiCad design in my own project?
Its repository states no licence, so its author keeps all rights: ask ChrisLeoLeo before reusing the design.
