What’s published

Schematics published

MeowKit-S3's docs site publishes per-block schematic diagrams (power, MCU, display, audio, etc.) as images, but no downloadable KiCad/Gerber PCB source or BOM.

Research notes

docs.meowkit.cc/schematics (verified 200) shows per-block schematic *images*, not a single PDF or editable PCB source; no Gerbers/BOM found. The GitHub org actively publishing MeowKit-S3 firmware/docs/installer is 'mingolucky', not 'whitecliff' as given in the batch source; 'MeowKit' brand/domain (meowkit.cc, docs.meowkit.cc) matches the product in both.
