Questions
How big is the ECU SMD PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ECU SMD use?
133 parts, built around the LMV321, ADUM1201AR, AMS1117-5.0 and AMS1117-3.3. 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 ECU SMD KiCad files?
From the ASURacingTeam/EV19-SafetyShutdown repository on GitHub, at the commit this page was made from: the board is ECU_SMD/ECU_SMD.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ECU SMD 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).
