Questions
How big is the Clock pcb PCB?
It measures 133.9 × 66.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Clock pcb use?
51 parts, built around the ESP32-S3-MINI-1-N8, 3310Y-001-103L, D3V3XA4B10LP and GSB1C41110SSHR. 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 Clock pcb KiCad files?
From the laoeked1111/esp32-clock repository on GitHub, at the commit this page was made from: the board is clock-pcb/clock-pcb.kicad_pcb and its schematic clock-pcb/alarm.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Clock pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask laoeked1111 before reusing the design.
