Questions
What parts does the Smart power strip use?
44 parts, built around the ESP32-WROOM-32, RAC20-05SK and MAX1811ESA+. 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 power strip KiCad files?
From the jvcByte/sen382-PCB-circuit repository on GitHub, at the commit this page was made from: the board is smart_power_strip/smart-power-strip.kicad_pcb and its schematic 4x8x8-LED-Matrix-Display/4x8x8 LED Matrix Display/4x8x8 LED Matrix Clock.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Smart power strip design in my own project?
Its repository states no licence, so its author keeps all rights: ask jvcByte before reusing the design.
