## Blueprint

**Schematics published.** M5Stack publishes a CoreS3-family schematic PDF (shared with base CoreS3) and a 3D case STL for the Lite variant; no PCB source or BOM.

_Notes:_ docs.m5stack.com/en/core/CoreS3-Lite links out to the same schematic PDF used for the base CoreS3 (no Lite-specific schematic found); the STL is Lite-specific and confirmed in m5stack/M5_Hardware under K128-Lite_CoreS3-Lite.
