Questions
How big is the Canbus PCB?
It measures 58 × 58.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Canbus use?
47 parts, built around the ESP32-S3-WROOM-1-N8, R-78E5.0-1.0, ADS1015IDGS 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 Canbus KiCad files?
From the iot49/leaves-kicad repository on GitHub, at the commit this page was made from: the board is Leaves/Leaf_02/canbus.kicad_pcb and its schematic Leaves/Leaf_02/canbus.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Canbus design in my own project?
Its repository states no licence, so its author keeps all rights: ask iot49 before reusing the design.
