Questions
How big is the Stm32h743 can hs PCB?
It measures 99.1 × 53.3 mm and has 4 copper layers, 1.96 mm thick.
What parts does the Stm32h743 can hs use?
102 parts, built around the TCAN1044AVDRQ1, S25FL128LAGMFI013, ST1S40IPHR and USB3300-EZK. 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 Stm32h743 can hs KiCad files?
From the Kevinbot-Robotics/stm32h743_can_hs_dev repository on GitHub, at the commit this page was made from: the board is stm32h743_can_hs.kicad_pcb and its schematic stm32h743_can_hs.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stm32h743 can hs 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).
