Questions
How big is the Smart Wearable Device PCB?
It measures 40 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Smart Wearable Device use?
42 parts, built around the ESP32-C3-MINI-1-N4, MAX30102, TPS61092RSA and AMS1117-3.3. 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 Wearable Device KiCad files?
From the enoch-git/smart-wearable-device-pcb repository on GitHub, at the commit this page was made from: the board is Smart_Wearable_Device.kicad_pcb and its schematic Smart_Wearable_Device.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Smart Wearable Device design in my own project?
Its repository states no licence, so its author keeps all rights: ask enoch-git before reusing the design.
