Questions
How big is the ZenFly F71 PCB?
It measures 41.5 × 41.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ZenFly F71 use?
180 parts, built around the STM32F722RET6, ESP8285, SE2431L-R and SX1280IMLTRT. 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 ZenFly F71 KiCad files?
From the LongDo1902/STM32_Drone repository on GitHub, at the commit this page was made from: the board is ZenFlyF72_Refine/ZenFly F71.kicad_pcb and its schematic AnyLeaf/single radio schematic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ZenFly F71 design in my own project?
Its repository states no licence, so its author keeps all rights: ask LongDo1902 before reusing the design.
