Questions
How big is the Voice Control Light System PCB?
It measures 92 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Voice Control Light System use?
6 parts, built around the ESP32-C3-DEVKITM-1, ESP32-WROOM-32 and MAX3232ID. 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 Voice Control Light System KiCad files?
From the RathikaSeenivas/PCB_ASSIGNMENT repository on GitHub, at the commit this page was made from: the board is Voice_Control_Light_System.kicad_pcb and its schematic Voice_Control_Light_System.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Voice Control Light System design in my own project?
Its repository states no licence, so its author keeps all rights: ask RathikaSeenivas before reusing the design.
