## Blueprint

**Schematics published.** LILYGO's shared LilyGoLib repo has a PDF schematic for the T-Watch-S3-Plus GPS board; only minor strap-hook STL parts are published, no full case/PCB source.

### Key parts

| Part | Role | Datasheet |
|---|---|---|
| ESP32-S3 | MCU + Wi-Fi/BT | https://www.espressif.com/sites/default/files/documentation/esp32-s3_datasheet_en.pdf |
| SX1262 | LoRa radio | https://www.semtech.com/products/wireless-rf/lora-connect/sx1262 |

_Notes:_ Only the watch strap hook is published as a 3D file (case/t-watch/); the full watch case/PCB is not in the tree. Schematic file naming ('-GPS') confirms this covers the S3-Plus GPS variant.
