Questions
How big is the Esp drone PCB?
It measures 32.9 × 45.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp drone use?
13 parts. 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 Esp drone KiCad files?
From the tyrobee/Esp_fly repository on GitHub, at the commit this page was made from: the board is FC PCB/esp drone.kicad_pcb and its schematic FC PCB/esp drone.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp drone design in my own project?
Its repository states no licence, so its author keeps all rights: ask tyrobee before reusing the design.
