Questions
How big is the Supervisor PCB?
It measures 102.4 × 88.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Supervisor use?
49 parts, built around the ESP32-WROOM-32D, 74HC14, BSS138 and MMBT2222. 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 Supervisor KiCad files?
From the aprasan2000/ECE477 repository on GitHub, at the commit this page was made from: the board is supervisor_schematic/supervisor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Supervisor design in my own project?
Its repository states no licence, so its author keeps all rights: ask aprasan2000 before reusing the design.
