Questions
How big is the Smart watch PCB?
It measures 69.4 × 63.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Smart watch use?
52 parts, built around the STM32L152RET6, SHT21 and LS013B7DH03. 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 watch KiCad files?
From the wpmyj/KICAD_SmartwatchPCB repository on GitHub, at the commit this page was made from: the board is Smartwatch_PCB/Smart watch.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Smart watch design in my own project?
Its repository states no licence, so its author keeps all rights: ask wpmyj before reusing the design.
