## Blueprint

**Closed design.** T-Echo Plus (new, ~Dec 2025) has no published schematic, PCB, or 3D files yet; LILYGO's own documentation page shows placeholder/empty hardware sections and only links back to the base T-Echo repo.

### Key parts

| Part | Role | Datasheet |
|---|---|---|
| nRF52840 | MCU + BLE | https://www.nordicsemi.com/Products/nRF52840 |
| SX1262 | LoRa radio (433/868/915MHz) | https://www.semtech.com/products/wireless-rf/lora-connect/sx1262 |

_Notes:_ Confirmed via Xinyuan-LilyGO/documentation en/products/t-echo-series/t-echo-plus/index.md: the Schematic, Dimensions and PCB/enclosure sections contain only unfilled HTML-comment placeholders; the page links the base T-Echo GitHub repo and datasheets only, no Plus-specific hardware repo exists as of this check.

### Raw source files

Direct links an agent or KiCad can open (the viewer on the page reads the same files).
