Questions
How big is the Euroc controller PCB?
It measures 35.1 × 77 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Euroc controller use?
94 parts, built around the TCAN332D, LIS2MDL, MS5611-01BA03 and W25Q128JVSIQ. 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 Euroc controller KiCad files?
From the aesirkth/fjalar_flight_controller repository on GitHub, at the commit this page was made from: the board is design/euroc_controller.kicad_pcb and its schematic design/euroc_controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Euroc controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask aesirkth before reusing the design.
