Questions
How big is the CampusCast PCB?
It measures 63.5 × 45.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CampusCast use?
15 parts, built around the ESP32-WROOM-32 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 CampusCast KiCad files?
From the e-labInnovations/CampusCast repository on GitHub, at the commit this page was made from: the board is Hardware/Design/Design.kicad_pcb and its schematic Hardware/Design/Design.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CampusCast design in my own project?
Its repository states no licence, so its author keeps all rights: ask e-labInnovations before reusing the design.
