Questions
How big is the Dev board STM32H7 PCB?
It measures 40.9 × 68.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dev board STM32H7 use?
50 parts, built around the W25Q32JVSSIQ, AMS1117-3.3 and BAT54C. 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 Dev board STM32H7 KiCad files?
From the ykjoe/dev_board_STM32H7 repository on GitHub, at the commit this page was made from: the board is dev_board_STM32H7.kicad_pcb and its schematic HMI.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dev board STM32H7 design in my own project?
Its repository states no licence, so its author keeps all rights: ask ykjoe before reusing the design.
