- ERC: 0 errors. DRC: 22 unconnected GND items because CLI checks do not fill zones.
- Library remapping is required. Relay footprints are placeholders and must be corrected.
- Connector fit, motor current, relay rating, and relay polarity remain unverified.
- Do not order a board until layout checks and bench validation HV1–HV4 pass.
Reports: hardware/exports/erc.rpt and hardware/exports/drc.rpt.

Questions
How big is the Na wink PCB?
It measures 100 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Na wink use?
51 parts, built around the ESP32-S3, LM46002PWP, G2R-2-DC5 and MMBT2222A. 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 Na wink KiCad files?
From the rodriveiga01/mx5-light repository on GitHub, at the commit this page was made from: the board is hardware/kicad/na-wink.kicad_pcb and its schematic hardware/kicad/na-wink.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Na wink 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).
