Questions
How big is the DroneController PCB?
It measures 59.8 × 39.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DroneController use?
47 parts, built around the BMP280, AMS1117-3.3, L7805 and MPU-6050. 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 DroneController KiCad files?
From the Shubhkr08/DroneController repository on GitHub, at the commit this page was made from: the board is Drone Controller/PCB/DroneController.kicad_pcb and its schematic Drone Controller/PCB/DroneController.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DroneController design in my own project?
Its repository states no licence, so its author keeps all rights: ask Shubhkr08 before reusing the design.
