Questions
How big is the Wearablesystem PCB?
It measures 89.5 × 97.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wearablesystem use?
65 parts, built around the ESP32-C3, MAX30102, USBLC6-2SC6 and SPX3819M5-L-1-8. 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 Wearablesystem KiCad files?
From the manushri-d/ece445 repository on GitHub, at the commit this page was made from: the board is wearablesystem/wearablesystem.kicad_pcb and its schematic mounted_system/mounted_system.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wearablesystem design in my own project?
Its repository states no licence, so its author keeps all rights: ask manushri-d before reusing the design.
