Questions
How big is the Stud main PCB?
It measures 71 × 83 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Stud main use?
80 parts, built around the ESP32-WROOM-32D, LAN8710A-EZC, DS3232MZ+ and TLV1117-33DCY. 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 Stud main KiCad files?
From the Dimadeda/Smart-Faculty- repository on GitHub, at the commit this page was made from: the board is stud_main/stud_main.kicad_pcb and its schematic stud_main/stud_main.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stud main design in my own project?
Its repository states no licence, so its author keeps all rights: ask Dimadeda before reusing the design.
