Questions
How big is the STM32H503CBT6 PCB?
It measures 18 × 50 mm and has 4 copper layers, 1.6 mm thick.
What parts does the STM32H503CBT6 use?
37 parts, built around the STM32H503CBT6, RT9078-33GQZ, AO3401A and BAV70. 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 STM32H503CBT6 KiCad files?
From the r-pv/STM32H503CBT6 repository on GitHub, at the commit this page was made from: the board is STM32H503CBT6/STM32H503CBT6.kicad_pcb and its schematic STM32H503CBT6/STM32H503CBT6.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32H503CBT6 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
