Questions
How big is the Aviyonik PCB?
It measures 69.8 × 71.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Aviyonik use?
133 parts, built around the TCAN1044VDRQ1, INA226AIDGST, MMC5983MA and MS5611-01BA03. 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 Aviyonik KiCad files?
From the basarbinici/4-Layered-Flight-Controller-PCB repository on GitHub, at the commit this page was made from: the board is aviyonik/aviyonik.kicad_pcb and its schematic aviyonik/aviyonik.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Aviyonik design in my own project?
Its repository states no licence, so its author keeps all rights: ask basarbinici before reusing the design.
