Questions
How big is the Stm32-can node PCB?
It measures 40 × 25 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Stm32-can node use?
53 parts, built around the SN65HVD234DR-JSM, DS2484R+T, BL-HB337A-AV-TRB and MHT136CRCT. 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 Stm32-can node KiCad files?
From the mrk-its/stm32-can-node repository on GitHub, at the commit this page was made from: the board is stm32-can-node.kicad_pcb and its schematic misc.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stm32-can node design in my own project?
Its repository states no licence, so its author keeps all rights: ask mrk-its before reusing the design.
