Questions
How big is the Explore maple PCB?
It measures 26.3 × 52 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Explore maple use?
35 parts, built around the STM32F103C8T6 and BC547. 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 Explore maple KiCad files?
From the ExploreEmbedded/Alpine-Swift repository on GitHub, at the commit this page was made from: the board is AlpineSwift_Hardware/explore_maple.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Explore maple design in my own project?
Its repository states no licence, so its author keeps all rights: ask ExploreEmbedded before reusing the design.
