Questions
How big is the Stm32simh PCB?
It measures 80 × 80 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Stm32simh use?
96 parts, built around the STM32H753ZIT6, CP2102N-EK, IS61WV204816BLL-10TLI and LAN8720A-CP. 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 Stm32simh KiCad files?
From the bson/stm32simh repository on GitHub, at the commit this page was made from: the board is stm32simh.kicad_pcb and its schematic ethernet.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stm32simh 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).
