Questions
How big is the ESP32-CAN PCB?
It measures 92 × 95 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ESP32-CAN use?
251 parts, built around the CH340C, ESP32-WROOM-32D, TJA1050 and ULN2003. 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-CAN KiCad files?
From the Eric-2012/ESP32-CAN repository on GitHub, at the commit this page was made from: the board is PCB/ESP32-CAN/ESP32-CAN.kicad_pcb and its schematic PCB/ESP32-CAN/CAN CONTROLLER.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32-CAN design in my own project?
Its repository states no licence, so its author keeps all rights: ask Eric-2012 before reusing the design.
