Questions
How big is the CosmosBoard PCB?
It measures 203.2 × 100.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the CosmosBoard use?
124 parts, built around the STM32F405RGT6, BMP280, AMS1117-3.3 and BNO055. 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 CosmosBoard KiCad files?
From the BaktiyarBr/ElectronyConstructor repository on GitHub, at the commit this page was made from: the board is CosmosBoard/CosmosBoard.kicad_pcb and its schematic CosmosBoard/CosmosBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CosmosBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask BaktiyarBr before reusing the design.
