Questions
How big is the RedPill board PCB?
It measures 25.4 × 80.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RedPill board use?
63 parts, built around the STM32F401RCT6, AMS1117-3.3 and S9013. 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 RedPill board KiCad files?
From the simonyiszk/STM32-RedPill repository on GitHub, at the commit this page was made from: the board is RedPill_board/RedPill_board.kicad_pcb and its schematic RedPill_board/RedPill_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RedPill board design in my own project?
Its repository publishes it under the CERN-OHL-W-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
