### Key parts

| Part | Role | Datasheet |
|---|---|---|
| ESP32-S3 | MCU | https://www.espressif.com/sites/default/files/documentation/esp32-s3_datasheet_en.pdf |
| Semtech SX1262 | LoRa radio, +22 dBm | https://www.semtech.com/products/wireless-rf/lora-connect/sx1262 |
| u-blox MIA-M10Q | GNSS/GPS |  |

_Notes:_ Repo README confirms this matches the retail 'T-Deck-MAX' product (MCU ESP32-S3, LoRa SX1262, GPS MIA-M10Q, display GDEQ031T10). The schematic file itself is oddly named 'T-Deck Pro Max V0.1 25-09-11.pdf' inside the T-Deck-MAX repo — an internal LILYGO naming inconsistency, but the file's location (Xinyuan-LilyGO/T-Deck-MAX/hardware/) and repo README confirm it is the T-Deck-MAX schematic. URL verified live (200).
