Questions
How big is the YNXT WM01 PCB?
It measures 87.6 × 35.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the YNXT WM01 use?
45 parts, built around the E18-MS1-PCB, STI3408B, DW01A and FS8205A. 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 YNXT WM01 KiCad files?
From the RJSDevel/YNXT-WM01 repository on GitHub, at the commit this page was made from: the board is Hardware/YNXT-WM01.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the YNXT WM01 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).
