Questions
How big is the CapstoneDronePCBV2 PCB?
It measures 40.5 × 40.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the CapstoneDronePCBV2 use?
53 parts, built around the STM32F103C8T6, PCA9685PW, AMS1117-3.3 and AMS1117-5.0. 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 CapstoneDronePCBV2 KiCad files?
From the landodoughty/Flight-Controller repository on GitHub, at the commit this page was made from: the board is CapstoneDronePCBV2.kicad_pcb and its schematic CapstoneDronePCBV2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CapstoneDronePCBV2 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
