Questions
How big is the Awatch2 PCB?
It measures 73.4 × 72.7 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Awatch2 use?
177 parts, built around the APDS-9306-065, BMM150, BMP388 and DRV2604YZF. 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 Awatch2 KiCad files?
From the jwise/aWatch2-hw repository on GitHub, at the commit this page was made from: the board is awatch2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Awatch2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask jwise before reusing the design.
