Questions
How big is the Smart Parking System PCB?
It measures 150 × 135 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Smart Parking System use?
54 parts, built around the ESP32-DEVKITC-VE, 74HC165D and 74HC595. 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 Smart Parking System KiCad files?
From the chdsolinap/ece-projects repository on GitHub, at the commit this page was made from: the board is Smart Parking System/PCB/main-board/main-board.kicad_pcb and its schematic 4-bit Full Adder/4_bit_full_adder_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Smart Parking System design in my own project?
Its repository states no licence, so its author keeps all rights: ask chdsolinap before reusing the design.
