Questions

How big is the ZSWatch Watch DevKit PCB?

It measures 100 × 70 mm and has 4 copper layers, 1.58 mm thick.

What parts does the ZSWatch Watch DevKit use?

132 parts, built around the NORA-B106-00B, APDS-9306-065, BMP581 and FAN5622SX. 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 ZSWatch Watch DevKit KiCad files?

From the ZSWatch/Watch-DevKit-HW repository on GitHub, at the commit this page was made from: the board is devkit/ZSWatch-Watch-DevKit.kicad_pcb and its schematic devkit/Block Diagram.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the ZSWatch Watch DevKit design in my own project?

Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
