## Blueprint

**Closed design.** Seeed publishes only a product datasheet/user guide for the T1000-E card tracker; no schematic, PCB source, or 3D files are published for the tracker itself.

### Design files

- manual: [Product datasheet (PDF)](https://files.seeedstudio.com/products/SenseCAP/SenseCAP_Tracker_T1000_Datasheet.pdf) (PDF)

### Key parts

| Part | Role | Datasheet |
|---|---|---|
| Nordic nRF52840 | MCU/BLE radio | https://files.seeedstudio.com/wiki/XIAO-BLE/nRF52840_PS_v1.5.pdf |
| Semtech LR1110 | LoRa/GNSS transceiver | https://www.semtech.com/products/wireless-rf/lora-edge/lr1110 |
| MediaTek/Airoha AG3335 | multi-GNSS receiver |  |

_Notes:_ Datasheet URL confirmed 200 via curl. Web search found no schematic/KiCad/Gerber files for the T1000-E card tracker; the similarly-named Seeed-Studio/Seeed-Tracker-T1000-E-for-LoRaWAN-dev-board GitHub repo is firmware/SDK examples only, not hardware design files, and covers the separate LoRaWAN dev-board SKU.

### Firmware & setup

| | |
|---|---|
| Model requirement | Use the T1000-E for Meshtastic model; T1000-A/B use different firmware. |
| Same-name LoRaWAN variant | T1000-E for LoRaWAN is also sold. Seeed warns against flashing Meshtastic or MeshCore firmware to it. |
| Updates | USB DFU/UF2; maker warns against NRF-OTA |
| Telemetry support | Temperature is supported; guide marks light unavailable in the app and accelerometer support pending. |
| Mesh setup | Match region, modem preset and channel settings with your nodes |
| First power-up | Press once; startup gives a rising tone and roughly one second of LED light. |
| Client connections | Phone over Bluetooth; web client over Bluetooth or USB serial |
| Firmware target | Seeed Card Tracker T1000-E in the Meshtastic flasher |
| DFU indication | Solid green LED and a T1000-E USB drive indicate DFU mode. |
