Questions
How big is the Mini Drone PCB?
It measures 55 × 47 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Mini Drone use?
74 parts, built around the ESP32-S3-WROOM-1-N8, SPX3819M5-L-3-3, AO3400A and SS34. 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 Mini Drone KiCad files?
From the GitHubKailash/Mini-Drone-Custom-PCB repository on GitHub, at the commit this page was made from: the board is Mini_Drone.kicad_pcb and its schematic Mini_Drone.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mini Drone design in my own project?
Its repository states no licence, so its author keeps all rights: ask GitHubKailash before reusing the design.
