Questions
How big is the My STM32 PCB?
It measures 53.3 × 35.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the My STM32 use?
31 parts, built around the AMS1117. 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 My STM32 KiCad files?
From the Vtechcode/my-STM32 repository on GitHub, at the commit this page was made from: the board is Hardware/my-STM32.kicad_pcb and its schematic Hardware/my-STM32.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the My STM32 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Vtechcode before reusing the design.
