Questions
How big is the ELEC3300 FinalProject PCB?
It measures 84.3 × 134.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ELEC3300 FinalProject use?
139 parts, built around the TJA1042T/3/1J, INA240A1D, RY8411 and CH343P. 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 ELEC3300 FinalProject KiCad files?
From the guajun/ELEC3300_FinalProject repository on GitHub, at the commit this page was made from: the board is HW/ELEC3300-Final_Project.kicad_pcb and its schematic HW/ELEC3300-Final_Project.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ELEC3300 FinalProject design in my own project?
Its repository states no licence, so its author keeps all rights: ask guajun before reusing the design.
