Questions
How big is the PCB Main Final PCB?
It measures 190.5 × 83.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PCB Main Final use?
119 parts, built around the ESP32-WROVER-E(4MB), LM4752TS, AMS1117-3.3 and PCM5102APW. 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 PCB Main Final KiCad files?
From the ERZehr/SeniorDesign repository on GitHub, at the commit this page was made from: the board is PCB/Main_PCB/PCB_Main_Final.kicad_pcb and its schematic PCB/Light_Sensor/Light_Sensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCB Main Final design in my own project?
Its repository states no licence, so its author keeps all rights: ask ERZehr before reusing the design.
