M5Stack publishes schematic PDFs for the Unit C6L board and its embedded Stamp-C6LoRa module, plus a 3D case STL; the Stamp module additionally has full Altium source, but the Unit board itself does not.

Research notes

Confirmed via WebFetch of docs.m5stack.com/en/unit/Unit_C6L and gh tree of m5stack/M5_Hardware. Unusual case: the carrier-board (Unit C6L) is only schematic-level open, but the radio daughter-module inside it (S012 Stamp-C6LoRa) ships true editable Altium PCB source (SchDoc+PcbDoc+PcbLib+SCHLIB+STEP) in the same MIT-licensed repo.
