Questions
How big is the StandardModuleV2 PCB?
It measures 40 × 26.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the StandardModuleV2 use?
41 parts, built around the SM24CANB-02HTG, B260, PRTR5V0U2AX-ES and SMAJ18CA. 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 StandardModuleV2 KiCad files?
From the ilicmiljan/open-can-controller repository on GitHub, at the commit this page was made from: the board is hardware/stm32/StandardModuleV2.kicad_pcb and its schematic hardware/avr/B CAN Module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the StandardModuleV2 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).
