Questions
How big is the ESP32-DualCAN PCB?
It measures 38.8 × 19.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32-DualCAN use?
34 parts, built around the DSK38, SMF30CA and SMF58A. 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 ESP32-DualCAN KiCad files?
From the dzid26/ESP32-DualCAN repository on GitHub, at the commit this page was made from: the board is hardware/ESP32-DualCAN.kicad_pcb and its schematic hardware/ESP32-DualCAN.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32-DualCAN design in my own project?
Its repository publishes it under the CERN-OHL-W-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
