## Blueprint

**Schematics published.** Seeed publishes the schematic PDF and chip datasheet for the XIAO ESP32C6; the related GitHub repo has only a footprint/pinout library, not the module's own PCB source.

### Key parts

| Part | Role | Datasheet |
|---|---|---|
| Espressif ESP32-C6 | MCU (dual RISC-V core, Wi-Fi 6/BLE/802.15.4) | https://www.espressif.com/sites/default/files/documentation/esp32-c6_datasheet_en.pdf |

_Notes:_ Same OSHW-XIAO-Series caveat as the other XIAO boards in this batch: it's a footprint/pinout reference library, not the module's own editable PCB source.

## Specifications
