Questions
How big is the STM32-LED Heart PCB?
It measures 101.1 × 83.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the STM32-LED Heart use?
43 parts. 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 STM32-LED Heart KiCad files?
From the Essenter24/STM32-LED-Heart repository on GitHub, at the commit this page was made from: the board is Hardware/STM32 LED Heart.kicad_pcb and its schematic Hardware/STM32 LED Heart.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32-LED Heart design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
