Questions
How big is the Esp32 smart clock PCB?
It measures 104.5 × 67 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp32 smart clock use?
68 parts, built around the ESP32-S3-WROOM-1-N8, BME280, AZ1117CH-3.3TRG1 and RB161MM-20TR. 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 Esp32 smart clock KiCad files?
From the rokube015/esp32_smart-clock repository on GitHub, at the commit this page was made from: the board is HW/PCB/PCB.kicad_pcb and its schematic HW/PCB/PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32 smart clock design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
