Questions
How big is the Controller PCB?
It measures 50 × 75 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Controller use?
22 parts, built around the ESP32-DEVKITC-32E, AMS1117-3.3, AMS1117-5.0 and SP3485EN-Y. 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 Controller KiCad files?
From the zuhayrl/EEE4022S_Thesis repository on GitHub, at the commit this page was made from: the board is PCB/Controller/controller_v1-0/controller.kicad_pcb and its schematic Diagrams/report_diagrams/report_diagrams.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask zuhayrl before reusing the design.
